... Suppose you hang a 5 Newton weight from a string, and hold the other end of the string in your hand. If the weight (and the string and your hand) is at rest, then the weight exerts a 5 N downward force on the lower end of the string, and you exert a 5 N upward force on the upper end of the string.

... 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 ...
