Kinetic energy

• A moving object can do work
• An object moving faster can do more work than an identical object moving relatively slow
• Moving objects that can do work

  • a moving bullet
  • blowing wind
  • a rotating wheel
  • a speeding stone
• How a bullet pierces the target

  The bullet possesses kinetic energy
• How the wind moves the blades of a windmill

  The wind possesses kinetic energy
• Kinetic energy


  The energy possessed by an object due to its motion
• Objects that possess kinetic energy


  • a falling coconut
  • a speeding car
  • a rolling stone
  • a flying aircraft
  • flowing water
  • blowing wind
  • a running athlete
