"If a student learns about writing an equation to describe a picture or a pattern, it will help him or her understand how graphs and equations work and how they apply to the real world. Writing an equ ...
"Newton's Law of Universal Gravitation says that everything with massive particle in the universe attracts all other massive particles. This force is called gravity. The force of gravity = universal g ...
"Conservation of energy, sometimes called the first law of thermodynamics, states that energy can neither be created nor destroyed. Energy, however, can be transferred from one form to another." Fuent ...
"The gaseous state is one of the three phases of matte. Gases are obtained through vaporization from liquid and sublimation from solid. When a liquid vaporizes, it is often called boiling. Gases are t ...
"According to Newton’s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. S ...

"According to Pascal's Principle, in a uniform fluid, pressure depends only on height. There can be no pressure gradient except for that caused by liquid pressure. This is seen in hydraulic jacks whic ...
"Cell walls are only found in plant cells and are used primarily to create structure, but cell membranes are found in all cells. The bulk of the membrane is composed of a double layer of lipids called ...
"Heat of fusion is the energy needed for one gram of a solid to melt without any change in temperature. Heat of vaporization is the energy needed for one gram of a liquid to vaporize (boil) without a ...
