Front

What happens to the potential energy of an object as it is lifted higher above the ground?

Back

It increases

Front

Example of chemical potential energy: A moving car, A compressed spring, A battery, A rock at the top of a hill

Back

Front

How does the speed of an object affect its kinetic energy?

Back

Kinetic energy increases when speed increases

Front

Which of the following best describes the law of conservation of energy?

Back

Energy can be transformed from one form to another, or transferred to another object

Front

A ball is dropped from a height. As it falls, what happens to its potential and kinetic energy?

Back

Potential energy decreases, kinetic energy increases

Front

Example of gravitational potential energy: A stretched rubber band, A book on a shelf, A moving bicycle, A charged battery

Back

A book on a shelf
