Elastic Potential Energy
... The total energy is neither increased nor decreased in any process. Energy can be transformed from one for to another, and transferred from one object to another, but the total amount remains constant. In a process, mechanical energy may be “lost” or “gained” due to the work that is done by nonconse ...

What is Newton`s Third Law
... What are Action and Reaction Forces? • Newton’s 3rd law applies to driving because when you drive the action force is the pushing against the road and the reaction is the road pushing against the tires. Also when a car hits a person, the person hits the car. When a car hits telephone pole the pole ...
