Does potential energy move?

Back

No, because potential energy is stored energy not the energy of movement.

What is the relationship between potential and kinetic energy in a roller coaster?

Back

As a roller coaster goes up, potential energy increases and kinetic energy decreases; as it goes down, potential energy decreases and kinetic energy increases.

What role does friction play in energy?

Back

Friction converts kinetic energy into thermal energy, causing no movement.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.
