Energy

Cards (7)

  • Conservation of energy means energy is never lost, but converted from one form to another
  • The energy change when an object is lifted is work done to gravitational potential energy
  • The energy change when an object falls is gravitational potential energy to kinetic energy
  • Work done is the energy used when a force is applied over a distance
  • Gravitational potential energy is the energy gained by an object when lifted to a height
  • Kinetic energy is the energy stored by a moving object
  • When work is done against friction, energy is changed into heat and sound
