A group of students built a ramp and rolled steel balls of different sizes down the ramp onto the floor. Then they measured how far each ball rolled from the bottom ol the ramp.
Ramp Experiment Results
Mass of Steel Ball Distance Rolled
5.3 grams
1.2 meters
8.5 grams
2.0 meters
12.4 grams
3.1 meters
15.8 grams
3.9 meters
Which statement correctly explains the differences in the distances that the balls rolled?
O Friction increased as mass increased
O Velocity increased as mass increased.
Acceleration increased as mass increased.
Kinetic energy increased as mass increased.
