Kinetic Energy

• Kinetic energy is the energy stored in moving objects>
• Stationary objects have no kinetic energy
• $E_k =$$0.5 *$$m *$$v^2$


  Ek = Kinetic energy

  m = mass (kg)

  v2 = speed (m/s)
• A car is travelling at a constant speed

  1. Chemical energy store in petrol ...
  2. ... Kinetic energy store
• A car with a mass of 700kg is moving with the speed of 20m/s. Calculate the kinetic energy of the car.
• Divide joules by 1000 to get kJ
