Does Mass Make a Difference? $100 Does Mass Make a Difference? 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 Identify which ball will push the box the farthest.

$100 Part A Ball C will push the box the farthest. Scores

Does Mass Make a Difference? $200 Does Mass Make a Difference? 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 B. Explain why the ball you chose in part A will push the box the farthest distance.

$200 Part B Ball C will push the box the farthest distance because it has the greatest mass (30 grams) of all 3 balls. Since the ramps and empty boxes in all 3 situations are the same size, shape, and weight, the ONLY variable that is different is the mass of the balls. Since Ball C has the greatest mass, it will also have the greatest momentum (speed) as it rolls down the ramp. Ball C will apply more force to make the box move. Therefore, the empty box will move the farthest when Ball C hits it. Scores

Does Mass Make a Difference? $300 Does Mass Make a Difference? 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 C. Describe one change that Michael can do to make the box you chose travel farther.

$300 Part C One change Michael can do to make Box C travel farther is: Reduce the friction on the surface of Ramp C by adding a lubricant such as oil, hand-soap, etc. Increase the height of the ramp, make it steeper. Apply more force to Ball C. Push Ball C with more force with your hand. Get a ball with more mass than 30 grams to roll down the ramp and hit the box. Get a box with less mass or weight for Ball C to hit against it at the bottom of the ramp. Scores
