What is the formula for gravitational potential energy (GPE)?

Back

GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

If two objects are moving at the same speed, how can you determine which has greater kinetic energy?

Back

The object with greater mass will have greater kinetic energy.

Front

What is the effect of doubling the speed of an object on its kinetic energy?

Back

Kinetic energy increases by a factor of four (since KE is proportional to the square of the speed).
