In position D, the pendulum ball has a combination of potential energy and kinetic energy. Potential energy is stored energy due to the height of the ball above its lowest point (position G) and is maximum when the ball is at its highest point (position A). As the ball swings down towards position D, its potential energy gradually decreases and gets converted into kinetic energy.
Kinetic energy is the energy possessed by an object due to its motion. In position D, the ball has reached its maximum velocity as it swings downwards, resulting in the highest kinetic energy of the pendulum cycle. This kinetic energy is a result of the conversion of potential energy and the pendulum ball's continuous acceleration due to gravity.
Overall, in position D, the energy of the pendulum ball is predominantly in the form of kinetic energy, with little potential energy left due to the reduced height compared to position A.
A Pendalin is swung from position A to the position G- describe the energy of the pendulum ball in position D
