at 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?

at 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 (m) is mass, (g) is gravitational acceleration and (h) is height.

Step2: Compare heights at A and B

The height (h) is greater at point B. So, potential energy is greater at B.

Step3: Analyze energy - change from B to A

As the swing moves from B to A, height (h) decreases. According to (U = mgh), potential energy decreases. Since total mechanical energy (sum of kinetic and potential energy) is conserved in the absence of non - conservative forces, kinetic energy increases.

Answer:

  1. B
  2. Kinetic
