Let’s think about this step by step.
We see a pendulum swinging from left to right. The positions are labeled A, B, C, D, and E.
- Position A is the farthest left.
- Position E is the farthest right.
- Position C is in the middle — straight down.
- Positions B and D are between the ends and the center.
In a pendulum swing:
→ At the highest points (A and E), the pendulum stops for a split second before changing direction. That means its speed is zero there. So kinetic energy is also zero at A and E.
→ As it swings down toward the center (C), it speeds up. Gravity pulls it down, turning potential energy into kinetic energy.
→ At the lowest point (C), it’s moving the fastest. That’s where kinetic energy is greatest.
→ Then as it goes up to D and E, it slows down again.
So, kinetic energy is highest when speed is highest — which is at position C.
Final Answer:
C
