On a smooth floor, a wooden ball and an iron ball of the same size are rolled with the same force. The iron ball travels a greater distance because—
- ait has less mass and so less inertia
- bit has greater mass and so greater inertia of motion (momentum)
- cthe wooden ball has more friction with air
- diron rolls naturally faster than wood
