Physics Tip

Viscosity
The property of a liquid that makes it resist flow or any change in the arrangement of its molecules. The higher the viscosity, the "thicker" a liquid seems.

Physics Quote

It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.
Sir Arthur Eddington (1882 - 1944)

The Concept of Energy

Reduced to simplest terms, the universe is nothing more than a series of energy exchanges. As in much of physics, the concept of energy is easy to understand, but difficult to express and work with.

Energy = The ability to cause change.

Notice the simplicity of this definition. If something has the ability to cause a change in the physical or chemical properties of another object it has energy. If we restrict our study to mechanical energy, then we consider the changes in the state of motion of an object.

There are different classifications of energy, usually named for the source of the force involved; mechanical, gravitational, electrical, nuclear, etc. Within each of these areas the energy is further classified as either potential or kinetic energy.

Potential energy - Energy due to an object’s position.

u need to slow it down alittle bit more, also you need to explain the equations, but it is a very good explenation.

you need to tell more about chemical energy so that i can copy so i can get a good grade but i cant use this stuff

If I was you, I would of made the article longer. That people could understand it better that is not as smart as you are.

This is a very good article. The only suggestion I would have is that you use a spell check program on the next one. Thanks, Chuck

Very well said. Now apply the same laws of nature that you have just stated to the electron found in the closed loop system of atoms and you will find gravity. Remenber that when an electron tunnels . It expresses no mass.
