Chapter 5 Work and Energy conclusion
... Energy can neither be created not destroyed, but can only be converted from one form to another. Heat energy is the kinetic or vibrational energy of molecules. The result of a non-conservative force is often to remove mechanical energy and transform it into heat. Examples of heat generation: sliding ...

Friction and Gravity
... Have you ever played catch with someone? If so, you have used PROJECTILE MOTION. Will a projectile object land on the ground at the same time as an object that is dropped down?? An object that is dropped and a object that a thrown from one side to another are BOTH in free fall and will hit the groun ...

These forces depend on friction; a person or car on ice, for example, may not be able to exert the action force to produce the needed reaction force. Which force we call action and which ...
