Physics: The Simple Pendulum
Pendulum Project
Pendulum蛇擺
Ballistic Pendulum VideoA classic physics lab with an impressive military history, the ballistics pendulum was invented in 1742 to measure the speed of bullets. It was later discovered that by knowing the weight of the pendulum, the weight of the shot fired and the distance the pendulum moved when struck, you then can calculate the velocity of the shot. Lead students in recreating this experiment to demonstrate conservation of energy, conservation of momentum and projectile motion. The pendulum consists of a spring gun, a ball that can be launched horizontally and a block to catch the ball. The pendulum swings to a maximum height where it is stopped. By measuring this height and using conservation of mechanical energy students can deduce the kinetic energy of the pendulum plus projectile immediately after they collide. A scale and pointer indicate the highest arc of the swing for accurate measurements every time. Includes instructions.

Topic :Understanding The Relation: ENERGY(P.E. and K.E.) and WORK

2009-02-19T03:05:00.000-08:00

Topic :Understanding The Relation: ENERGY and WORK (which is affected by FRICTION,GRAVITATION.)
Part 1: Introduction: Energy, Law of Conservation Of Energy
ENERGY!!!This is a video made for an Educational Media class on kinetic and potential energy.
The Law of Conservation of EnergyIn physics, the law of conservation of energy states that the total amount of energy in any isolated system remains constant but cannot be recreated, although it may change forms, e.g. friction turns kinetic energy into thermal energy. In thermodynamics, the first law of thermodynamics is a statement of the conservation of energy for thermodynamic systems, and is the more encompassing version of the conservation of energy. In short, the law of conservation of energy states that energy can not be created or destroyed, it can only be changed from one form to another or transferred from one body to another, but the total amount of energy remains constant (the same).
POTENTIAL ENERGY=KINETIC ENERGY [ But factors of friction or gravitation must be considered]
Moment of Inertia & Converting Potential Energy to Kinetic E

Part 2(A) What’s Potential Energy
Potential Energy is energy associated with height, kept in battery, spring in restrained state.
Physic: Potential Energy:
PE=mgh. The energy stored by moving a mass to a height above the surface of the earth, which turns into Kinetic Energy when dropped due to the force of Gravity.That's all well and good, but can you BREAK STUFF with it? SURE! At Slightly-Mad Science, we love breaking stuff!
Potential Energy

Energy - Gravitational Potential Energy

Part 2(B) What’s Kinetic Energy
Kinetic Energy is energy associated with movement
Conserve your frustration-energy and let us help you understand. Learn about kinetic energy, joules, the conservation of energy, and the work-kinetic energy principle
. Potential and Kinetic Energy
Mechanical Energy - Kinetic and PotentialA brief basic explanation about mechanical energy, potential energy and kinetic energy. the derivation of the formula and drill work. Stay tuned!
Part 3 Illustration of Potential Energy=Kinetic Energy
In theory if there is no friction or gravity or any external force (energy) acting on an object; the object either remain at inertial(stationary) or moving uniformly NON-STOP[Newton’s first and second law]. This is NEWTON’s LAW ON MOTION, but then it is still related to Thermodynamic THE LAW OF HEAT which establish this topic of POTENTIAL ENERGY=KINETIC ENERGY at the beginning of this study All in all , energy cannot be lost or created,it can only be transformed (as into light,heat,movement,sound…). THIS IS THE ZIST OF LAW OF CONSERVATION OF ENERGY. If energy cann’t be created, then how it comes into being? To me there’s a creator of universe!
Introduction to work and energy
Introduction to frictionCorrection of definition of "normal force" and an introduction to the coefficient of friction.
Friction on an inclined plane

Work/Energy problem with Friction
Kinetic and Potential Energy
Take a clock as an example:

(1)Battery=potential energy in the chemical-àHandle moves=kinetic energy,the WORK--- .[ 2 stages]
(2)If the clock/watch belonging to non-battery operated: The winding up(kinetic energy)THE WORK=Spring tighten up(potential energy)=the handle moves at each second(kinetic energy THE WORK )----[3 stages]
(3)Just a joke: When someone gets angry(potential energy) until cann’t bear it then blowing on somebody(kinetic energy).

Concave and Convex Lenses/Mirrors; Reflection and Refraction. Focal length

2009-02-18T22:51:00.000-08:00

First thing first: Differentiate the 2 types of LENSES and 2 tyese of MIRRORS(exlusive of PLANE mirror), and the type of images: REAL(can be caught on screen, size of image smaller and INVERTED eg. image fall on camera flilm) and VIRTUAL(image BIGGER and NOT INVERTTED--eg. MANIFYING GLASS), whether it is REFRACTIion or REFLECTION .Every lense has a focal lense, and their uses in every day life(eg.cameras,projectors,microscopes and telescopes,they use different types of lenses in certain fix combination). Always learn the relevent law or definition in physic, check and understand every element in the definition/law; then look for experiment ,application and do some exercises to make sure you can do in examinatuion. This is the proper way of learning science and any study! Always start with the basic though sometime may appear childish but it is fundamentally importance for further advancement in any study. Even though you could be very well versed in the topic(even as a PROFESSOR), ponder over it how could it be relatated to other topics or other subjects .Wish you the best in study in my blogS(I myself is doing the studying by learning more and more indept from each topic in ALL my blogs). Oh yes, please bookmark and share with your friends,teachers,and parents I would be very happy if you learn something in my blogs, this is my ONLY OBJECTIVE for "WASTING MY RESOURSES" here, afterall what can I get from anyone reading it/them!

The Science of Light

Physics, Science & Applications of Light, from 1950

The human eye may only be capable of seeing a small fraction of the electromagnetic spectrum that comes off the sun, but without this ability to see visible light portion of the spectrum we would be unable to function. Show Me Science: The Science of Light studies the light that the sun produces, and its effects on Earth's life forms. The program also demonstrates how a solar eclipse takes place, how light is reflected and seen by the human eye, and how light is much more than just a visual medium in its use as a communication tool in lasers.

cLearning About Heat (Highlights) – 1955
Temperature vs. HeatEureka! explains that heat refers to quantity of hotness, and is determined by the mass and speed of molecules. This program demonstrates that a bucket of water at a temperature of 50?C contains more heat than a cup of water at 100?C.
Heat as EnergyHeat is produced whenever there is movement and friction between two objects. Since movement is a form of energy, it follows that heat must also be a form of energy.
The expansion and contraction of liquidsTo show that water expands when heated and contracts when cooled
Expansion and ContractionUsing balloons to illustrate the process, Eureka! shows how, when matter gets hot, its molecules go faster and the solid, liquid, or gas expands. Conversely, when matter gets cold, its molecules go slower, and the solid, liquid, or gas contracts

Evaporation and Condensation Sublimation Process - A Chemistry Phenomenon Welcome to www.SimpleChemConcepts.com.
You have learnt about the 3 States of Matter - Solid, Liquid & Gas. We have also learnt about the physical processes that changes one state to another. e.g. Melting, Evaporation, Boiling, Condensation, Freezing, etc..
Sublimation is a very special process which changes the solid state directly into the gaseous state without going through Melting process (i.e. without going through the liquid state).
In this video, we share with you one of the everyday life examples that such Chemistry Phenomenons are observed.
This is Solid Carbon Dioxide, and in general we call it as Dry Ice. Dry Ice is a classic example that we observe sublimation process to occur. The solid carbon dioxide changes directly into gaseous carbon dioxide, without going through the liquid state.
Dry Ice is commonly used to keep Ice-Cream cold and solid by ice-cream vendors. Do you have any idea why we don't use normal ice (made of water) to keep ice cream cold?

2009-02-16T21:09:00.001-08:00

In what way they are interrelated? We may be involved in study and practice in the field of ELECTRICITY, CHEMISTRY , BIOCHEMISTRY I think the basic fundamental concept to SEE their RELATIONSHIP and how they overlap/integrate with one another in application of these fundamental knowledge:
1.ELEMENT=smallest unique building UNIT of a molecules which form A SUBSTANCE. In biology the MAIN COMPONENT and BY NATURE is PROTEIN UNIT which is THE CELL. (Note:Substance can exist in the state of SOLID, LIQUID and GAS).
2.BONDS=These are forces binding the ATOM or/and MOLECULES together, the forces have charges(the net effect of electrons and protons charges)s like electricity.
3.ELECTRICITY=Flow of electrons which are NEGATIVE CHARGE in a media(in a conductor like wire in a SOLID substance, or ELCECTROLYTE which is salts in PASTE/LIQUID or even in GASEOUS state.
4.MATTER/SUBSTANCE=Always trys to achieve in itself a STABLE STATE(neutral), so when in the INBALANCE STATE they EITHER giving away or receiving the electrons.
5BIOCHEMISTY=Is a study of a substance in the CHEMICAL(organic/inorganic chemical properties) and BIOLOGICAL ASPECTS(which involves elements of protein in nature)
6.PERIODIC TABLE=Classify activity/reactivity of an ATOM in the list.
This is meant for our CHIT-CHAT at my sun-set living, having consumed so much rice and salts,I see the health world in the deplorable confusing state by so called EXPERTS/PROFESSORS. One day my biochemist friend who is a professor told a joke: When I am asked by people what I am doing, I always say it is very hard for you to understand, as a biochemist I am involved in BIOLOGY and CHEMISTRY, somtimes I also get confused by BIOLOGY and CHEMISTRY--Some student may ask me from a biological aspect the other one on chemical aspect.
The significance of this joke=In healthwise, daily one group is harping the importance of VITAMINS AND MINERALS(chemicals) and the other group is harping on BIOLOGY(PROTEINS). But I still need to come across someone who can consistently gives me a comprehensive explaination HOW THE 2 GROUPS WORKS TOGETHER AS A WHOLE!
I think my biochemist friend is sincere and honest by this simple math: 100%BIOCHEMIST=X% BIOLOGIST + Y% CHEMIST. Pause for a while on this simple math to see the different professions in dept.

There’s another joke by a professor when I greeted him:”Hi Professor!” He answered me”What? Do you know what is a professor? Well, a professor no doubt is good in HIS AREA OF KNOWLEDGE,but could be the most STUBBORN and ARROGANT PERSON when we are discussing about LIFE!!, Do you know long time ago how people get their PHD, they did a lot of travelling around propounding their ideas ,mingled and study among the people in the world. Well, Michael you make a better professor( I AM NOT A PROFESSOR ANYWAY) because you can give better idea overall and afterall!”----Disclaimer: I am truly nobody and keep my profile as nobody(as a man who knows his creator and His purpose of creating me for my existing here ob earth), but the justice you decide as a jury for my working life 30 years in UNIVERSITY MALAYA and 5 years in UCSI practically all the office colleagues cal me all sort of names—I talk NO-SENSENSE and do NO-SENSE. Even sending me to see psychiatrist --IF I WANT TO KEEP MY RICE-BOWL, for pin-point me being a basic trouble causer in the department ,who talk and do NO-SENSE. Well, it is ok for me because THEIR SOULS are not on the same track with me moreover they have no switch to put on the SENSE in their SPIRIT. Friends, this is the world common apparent living but not the actual intrinsic life which the mind and heart should be outpouring and outflowing into reality FROM each individual living —For the UNDERSTANDING ONLY by those who have A RELIGION believing in SPIRIT and Mantraing about god/gods, other than teaching/preching SCIENCE. The objective of this CHIT-CHAT is to confide to my BLOG-READESRS AND ALL MY FRIENDS whosoever and whatsoever wandering what sort of person I am as many email me showing off their curiosity and well wishes. Well I am a very good joker and dramatic actor but always serious and keep silent NOT to let DECEPTION AND MISCONCEPTION to come in between JOKES AND FACTS. As usual my Simple N Easy for appreciate the worth of other person and myself is a short and sincere”THANK YOU” and “SORRY”. [NO non-sense also in the sense of sharp differentiation of diplomatic and politic elements in inviduality,because in our daily experience we are mature enough to elaborate DIPLOMATIC(nice, amicable,distinct socialable and mixable…but NOT GOOD morally and legally, based on a objective test which goes beyond SELF/EGO/PERSONAL INTEREST)is synonym to POLITIC. This is a paradox! ]----I keep my simple IQ, and genuine blogging in all my blogs. Please support me in my blogging by reading it yourself and recommend them to your friends.;even better if someone can come forward to host the blogs to benefit the world at large. In short, as a retirement man there’s a limit of resources II can contribute to the world in area of EDUCATION. I am smiling off with: Sorry and Thank you!

Sensory organs anatomy

NASA Anatomy : Sense Organs

The ear is the organ of hearing. The pinna of the outer ear collects sound waves and channels them along the external auditory meatus to the ear drum. The eardrum vibrates and mechanical waves are transmitted by the ossicles, three small bones of the middle ear-the malleus, incus and stapes-to the cochlea of the inner ear. The cochlea, a coiled tube filled with fluid, contains the organ of Corti. Fluid waves, created within the cochlea, excite nerve cells in the organ of Corti, which send impulses along the auditory nerve to the brain. The semicircular canals, the saccule and the utricle are concerned with balance and the posture of the body.

Voluntary muscles are The voluntary or skeletal muscle system consists of more than 650 muscles, which produce body movement and help maintain an upright posture. built onto the skeletal framework in several layers; the ones shown here are those directly under the skin. Facial muscles are involved in speech, eating, and expression. Muscles across the chest and the top of the back function in respiration and are also responsible for shoulder and arm movements. Muscles in the lower back help to maintain an erect posture. Abdominal muscles protect the internal organs. Arm and leg muscles, among the most powerful in the body, produce limb movements. Acting like cables, muscles pull on bones to produce movement. This involves the contraction and shortening of individual muscle fibers. Most of the body's voluntary muscles are arranged in opposing groups-as one muscle contracts the opposing muscle relaxes. Even when the body is being maintained in a relaxed position the muscles contract partially, but do not shorten. This maintains tone.

Get College Credit For Using YouTube

Have you ever wanted to get college credit just for watching videos on YouTube? Well, you can get pretty close at Pitzer College in Claremont, California. The course is called “Learning from YouTube” and students are encouraged to post their own videos as well as comment on others. Although students do have a set meeting time in a classroom, most of their work is done outside of class through the Learning from YouTube channel as well as through exploring the site.
I think it’s great that technology is being incorporated more and more into the classroom setting. It’s important for us to learn about new innovations and keep up with developments so that we can communicate effectively in our rapidly changing society. I would definitely be interested in taking a course like this if I was given the chance. I’ve always liked the concept of video websites and I’d definitely like to learn more about them. Watch for future postings from me about the impact of YouTube on our culture. Oh, and check out some of the other bizarre course offerings on the web. It seems like you can get credit for just about anything nowadays. My favorite? ”Shopping: Desire, Compulsion, and Consumption” at Williams College in Williamstown, Massachusetts, which will (oddly enough) get you religion credit. So keep an open mind during advance class selection this year and you could find yourself studying new technologies or at least discussing something important, like “The Simpsons and Philosophy.”[FROM: Heather’s Innovation and New Technologies Blog]

pH and pH indicators; Acid/Base and Titration

2009-02-14T11:09:00.000-08:00

here is alkali metals as they react with water.. for real! not fake :) If you like Cesium like I do, I have some interesting pictures on my wiki page you might like: http://en.wikipedia.org/wiki/User:Dnn87
Dont try it on your own –DANGEROUS!!

We are looking at the following acid-base indicators: methyl orange, methyl red, bromothymol blue, litmus, phenolphthalein and indigo carmine. Consider that these indicators all have their effective pH range at which they turn colours.dupuis.shawbiz.caUniversal indicator is a mixture of several indicators displaying a variety of colors over a wide pH range so it can be used to determine an approximate pH of the solution.Titration kits can help to mix lye in with the oil when making biodiesel; learn more from our biodiesel expert in this free alternative-fuel use video.

Education News
TITLE:Science lessons 'on YouTube'
27/11/2008
School science lessons are being hosted on YouTube in order to correct the British public's outdated views on the subject.
Five experiments are being carried out on the video-sharing website, with the most popular being conducted on a massive scale later this year.
The campaign is being launched by the Training and Development Agency for Schools (TDA), which aims to help recruit 6,600 extra science teachers over the next two years.
According to the TDA, 3,670 science teachers will be recruited in 2008/09, ahead of the government's target.
But Britons have an outdated view of science teaching, the agency said, citing its own research that showed 17 per cent of respondents thought lessons were enjoyable.
Just 28 per cent said the lessons were interesting, while 16 per cent said the equipment was modern.
Graham Holley, chief executive of the TDA, said the latest recruitment figures were "very encouraging".
"And for the first time ever, the TDA has beaten its annual recruitment target for science," he said.
"This is fantastic news and a testimony to the success of our recruitment campaign. It is great to see that we are attracting a record number of science trainees, and that our hard work is paying off.
"However, we must not be complacent. Over the next two years we need to recruit an additional 6,600 science teachers to meet the expected demand from schools. To do this, it is vital that the TDA continues to invest resources in attracting new and exciting talent to the profession. We need to encourage the best science graduates to become teachers, and this is what we will continue to do with the launch of today's campaign."
