Back

A hairdryer converts electrical energy into thermal energy (heat).

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 the stored energy of an object due to its position or state.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh, where PE is potential energy, m is mass, g is the acceleration due to gravity, and h is height.
