Which statement best compares potential and kinetic energy?
  • Work can transfer energy between objects and cause a change in the form of energy.
  • The skier has potential and kinetic energy.
  • The gas and food are examples of energy.
  • Only kinetic energy increases when the velocity of an object increases.
