makes the object move makes the object stay still pushes the object upward pulls the object downward
I gave my students this multiple choice question: What effect does gravity always have on an object on Earth?

Only one answer is correct among these 4 choices:
- makes the object move
- makes the object stay still
- pushes the object upward
- pulls the object downward

Could you tell me which one is correct?

pulls the object downward
