Physics Chapter 10 – Work, Energy, and Simple Machines What is
... What is energy? When you have a lot of energy you can run farther or faster; you can jump higher. Objects, as well as people, can have energy. A stone falling off a high ledge has enough energy to damage a car roof. One way to summarize the examples of energy above is to say that an object has energ ...

Forces and Motion: Newton`s Framework
... 4.1 Newton’s laws of motion When the forces add up to zero: the first law One of Newton’s breakthrough contributions was to see that it takes no force at all just to keep an object moving in a straight line with constant speed. A nonzero net force is there only when the motion changes in speed or dir ...
