Does the mass of the ball affect the distance a ball travels?
If we roll 3 different balls down the same ramp to measure the distance it rolls, then we think the metal ball will go the farthest distance because it has more mass than the other two.

Independent variable: We used different types of balls.
Constant: We used the same ramp for each trial.
To determine the average distance traveled for each ball, we added the total distance for all three trials and then divided the total by three.
