Kinetic and potential energy of pendulum, illustration
Illustration of a swinging pendulum, with the ball changing colour to show the relationship between potential energy and kinetic energy. At the top of its swing, the ball is stationary (zero kinetic energy) but has potential energy due to the force of gravity accelerating it down towards the floor. As it swings down its speed increases, meaning its kinetic energy rises and it turns purple. As it reaches the bottom of the swing it is travelling at its maximum speed and its kinetic energy is highest, and the ball is red. As it swings back upwards gravity decelerates it, reducing its kinetic energy until it is stationary at the top of the swing again. The energy converts from potential to kinetic and back again.
