What force slows some objects down? What force pulls objects to the ground? Do some objects fall more quickly than others? Do objects break or bounce when hitting the ground?
I gave my students this multiple choice question: A student is dropping objects of various sizes and shapes and recording the time it takes for each object to hit the ground. Which question is the student most likely trying to answer?

Only one answer is correct among these 4 choices:
- What force slows some objects down?
- What force pulls objects to the ground?
- Do some objects fall more quickly than others?
- Do objects break or bounce when hitting the ground?

Could you tell me which one is correct?

Do some objects fall more quickly than others?
