In the context of a pendulum's motion, energy conversions between potential energy and kinetic energy occur at different points in the swing of the pendulum:
- At the highest points of the swing (usually points like A or C), the pendulum has maximum potential energy and minimum kinetic energy.
- At the lowest point of the swing (like point B), the pendulum has maximum kinetic energy and minimum potential energy.
Given this understanding, the correct answer would be:
**D. Both points A and C**
This is because both points A and C represent positions where the pendulum has maximum potential energy, indicating energy conversions are taking place at those points as the pendulum swings between potential and kinetic energy.
- At the highest points of the swing (usually points like A or C), the pendulum has maximum potential energy and minimum kinetic energy.
- At the lowest point of the swing (like point B), the pendulum has maximum kinetic energy and minimum potential energy.
