An object is moving in a circular path. If its speed and radius are both doubled, what happens to its centripetal acceleration?
Q1. An object is moving in a circular path. If its speed and radius are both doubled, what happens to its centripetal acceleration?
Answer: It is doubled
Explanation: Centripetal acceleration = v² / r. When v is doubled and r is doubled, acceleration = (2v)² / (2r) = 2 * v² / r, so it is doubled.
