• Describe what is meant by kinetic energy.
• Calculate kinetic energy for a moving object.
Kinetic energy is the energy stored in moving objects.
Stationary objects have no kinetic energy.
Ek = 0.5 × m × v2
Examples:
1. A car with a mass of 700 kg is moving with a speed of 20m/s. Calculate the kinetic energy of the car.
2. A cyclist and bike have a total mass of 100 kg and a speed of 15 m/s. Calculate the kinetic energy.
3. A tennis ball is traveling at 50 m/s and has a kinetic energy of 75 J. Calculate the mass of the tennis ball.
