Question

consider the diagram of a pendulums motion shown above. a pendulum can be used to model the change from potential energy to kinetic energy and back to potential energy. according to the diagram, where are energy conversions taking place? a point a b point b c point c d both points a and c

Explanation:

At points A and C, the pendulum is at its maximum height in its swing. Here, it has maximum potential energy and minimum kinetic energy. As it moves from A to B or C to B, potential energy is converted to kinetic energy. At B, it has maximum kinetic energy and minimum potential energy. Then as it moves from B to A or B to C, kinetic energy is converted back to potential energy. So energy conversions are taking place at all points during its motion, including A and C.

Answer:

D. Both points A and C
