The kinetic energy of a rolling body is the sum of translation and:
ARadiation
BFriction
CRotation
DVibration
Answer & Solution
Correct answer: C. Rotation
1. A rolling body moves forward and spins at once.
2. Each kind of motion carries its own kinetic energy.
3. The total is the sum of translation and rotation.
