weight of the ball energy of the ball acceleration of the ball inertia of the ball
I gave my students this multiple choice question: A metal ball has a constant velocity of zero. Which other quantity must also be zero?

Only one answer is correct among these 4 choices:
- weight of the ball
- energy of the ball
- acceleration of the ball
- inertia of the ball

Could you tell me which one is correct?

acceleration of the ball
