SCIENCE OPEN RESPONSE
Does Mass Make a Difference?
25. Allison’s brother, Michael, needed an investigation for the Science Fair. He had three balls of
different masses. He decided to roll each ball down a ramp hitting an empty box at the bottom of
the ramp.
Ball A's Mass = 10 g
Ball B's Mass = 20 g
Ball C's Mass = 30 g
A. Identify which ball will push the box the farthest.
