Front

Define potential energy.

Back

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

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion.

Front

What is the relationship between potential and kinetic energy in a swinging pendulum?

Back

In a swinging pendulum, potential energy is highest at the top of the swing, while kinetic energy is highest at the lowest point.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often associated with heat.
