Mechanical Energy

Energy is one of the most important ideas in science. Energy allows us to live, think, move around, build, and communicate. What is energy? How does energy allow us to do work? How do machines make work easier? What happens to energy?

Standards Although the various forms of energy appear very different, each can be measured in a way that makes it possible to keep track of how much of one form is converted into another. Whenever the amount of energy in one place diminishes, the amount in other places or forms increases by the same amount. 4E/H1*
