Ac Hpat Physics Exam Solved 100% Correct!!

Chemical Energy {Ans: · Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place. Usually, once chemical energy has been released from a substance, that substance is transformed into a completely new substance.}Gravitational force {Ans: · The gravitational force is a force that attracts any two objects with mass. ... In fact, every object, including you, is pulling on every other object in the entire universe! This is called Newton's Universal Law of Gravitation.}Bernoulli's Principle {Ans: · Bernoulli's principle is an idea of fluid dynamics. It says that as speed of the fluid increases, pressure decreases. For a steady flow, the amount of fluid entering the pipe must equal the amount leaving the pipe, so the fluid speed in the thin part must increase.}Coefficient of friction {Ans: · A coefficient of friction is a value that shows the relationship between two objects and the normal reaction between the objects that are involved. ... The coefficient of friction depends on the objects that are causing friction. The value is usually between 0 and 1 but can be greater than 1.}gravitational potential energy
