Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion.

Front

What factors affect gravitational potential energy?

Back

Mass, height above the ground, and acceleration due to gravity.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as height increases.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with an increase in mass.
