A small diameter lead ball and a large diameter rubber ball are dropped from a tower. The balls hit the ground at the same time. What
conclusion can be drawn about the force of gravity?
es )
No conclusion can be drawn without more information about the two balls.
The rubber ball must have a greater gravitational force because it is larger.
The lead ball must have a greater gravitational force because it is more
dense.
They must have the same gravitational force because they hit the ground
at the same time.
