Potential and Kinetic Energy

Three friends were talking about energy. They were discussing the differences between potential and kinetic energy. Read what they said and choose who you agree with most.

• "I think potential energy is energy of motion and kinetic energy is energy of position."

• "I think potential energy and kinetic energy have no differences."

• "I think potential energy is energy of position and kinetic energy is energy of motion."

You are looking at a picture of a roller coaster moving down a large hill. You are trying to decide what is happening to the energy as the cart moves. Which answer is correct?

• The roller coaster cart is decreasing in potential energy and increasing in kinetic energy.

• The roller coaster cart is decreasing in kinetic energy and increasing in potential energy.

• The roller coaster cart is losing all of its energy.
