distinguishing between potential and kinetic energy\nat which position, a or b, is the potential energy of the swing the greatest?\nas the swing moves from point b to point a, which form of energy is increasing, kinetic or potential?
Answer
Explanation:
Step1: Recall potential - energy formula
Potential energy $U = mgh$, where $h$ is the height above the ground. Position B is higher.
Step2: Analyze energy change
As the swing moves from B to A, height $h$ decreases. Potential energy $U=mgh$ decreases and kinetic energy $K=\frac{1}{2}mv^{2}$ increases.
Answer:
- B
- Kinetic
