Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state.

Front

How does mass affect kinetic energy?

Back

More mass means more kinetic energy if speed is constant.

Front

How does speed affect kinetic energy?

Back

Higher speed means more kinetic energy if mass is constant.
