I gave my students this multiple choice question: Which is the best example of an object with kinetic energy?

Only one answer is correct among these 4 choices:
- a plate sitting on a table
- a bird perching in a tree
- a marble rolling down a ramp
- a dam holding back some water

Could you tell me which one is correct?

a marble rolling down a ramp
