Question

this diagram shows a baseball’s motion. which statement is best supported by the diagram?
○ kinetic energy becomes potential energy between points r and s.
○ maximum potential energy is at point p.
○ maximum potential energy is at point r.
○ potential energy becomes kinetic energy between points p and q.

Explanation:

1. Analyze each option:

• Option 1: Between R and S, the baseball is moving down, so potential energy (due to height) should convert to kinetic energy (due to motion), not the other way around. So this is incorrect.
• Option 2: Point P is the starting point, likely with lower height than R. Potential energy (gravitational) depends on height ($PE = mgh$), so P has less PE than R. Incorrect.
• Option 3: Point R is the highest point in the trajectory. Since $PE = mgh$, higher height means more PE. So maximum potential energy is at R. This is correct.
• Option 4: Between P and Q, the baseball is moving up, so kinetic energy (from P's motion) converts to potential energy (increasing height), not the other way. Incorrect.

Answer:

C. Maximum potential energy is at point R. (Note: Assuming the options are labeled as A, B, C, D with C being "Maximum potential energy is at point R" as per the third option in the list)
