Choose the correct claim: If a ball rebounds higher, it had more energy or less energy after the collision?
Choose the correct claim: If a ball rebounds higher, it had more energy or less energy after the collision?
Tap to reveal answer
More energy after the collision. Higher rebound means it retained or gained energy.
