Back

The energy an object possesses due to its motion, calculated as KE = 1/2 mv².

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height.

Front

What is mechanical energy?

Back

The sum of potential energy and kinetic energy in a system.
