Front

Define gravitational potential energy (GPE).

Back

The energy an object possesses due to its position in a gravitational field.

Front

What is the formula for gravitational potential energy?

Back

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

Front

What is kinetic energy (KE)?

Back

The energy an object has due to its motion.

Front

What is the formula for kinetic energy?

Back

KE = \frac{1}{2}mv^2, where m is mass and v is velocity.

Front

How does height affect gravitational potential energy?

Back

GPE increases with height.
