Kinetic Energy
Kinetic EnergyThis is the energy an object or particle has by reason of its motion. The formula for kinetic energy is:
From the equation it can be seen that the kinetic energy of a moving object or particle not only depends on its motion but also on its mass.
ExampleThe kinetic energy of a car of mass 1000kg travelling at 10 m/s can be calculated as: KE = ½ x 1000 x (10)2 KE = ½ x 1000 x 100 [remember (10)2 = 10 x 10] KE = ½ x 100000 KE = 50,000 Joules or 50 kilojoules (kJ)  |
