A stand shows a pendulum in 5 positions. A has the pendulum bob at a 45 degree angle to the left. C has the pendulum bob straight down, and B is halfway between A and C. E is has the pendulum bob at a 45 degree angle to the right, and D is halfway between C and E.
Determine how potential and kinetic energy changes at each position of the pendulum as the ball swings from A to E.
Position A:
Position B:
Position C:
Position D:
Position E:
Position A: At position A, the pendulum bob has potential energy at its maximum and kinetic energy at its minimum. This is because the bob is at its highest point and is not moving.
Position B: At position B, the pendulum bob has equal amounts of potential and kinetic energy. This is because the bob is halfway between its highest and lowest points and is moving with maximum speed.
Position C: At position C, the pendulum bob has potential energy at its minimum and kinetic energy at its maximum. This is because the bob is at its lowest point and is moving with maximum speed.
Position D: At position D, the pendulum bob has equal amounts of potential and kinetic energy. This is because the bob is halfway between its highest and lowest points and is moving with maximum speed.
Position E: At position E, the pendulum bob has potential energy at its maximum and kinetic energy at its minimum. This is because the bob is at its highest point and is not moving.
