Anika asks Eva to roll a basketball and then a bowling ball to her. Which requires more force to roll, and why?
Answer
A
the basketball, because it has more mass and therefore more inertia
B
the basketball, because it has less mass and therefore less inertia
C
the bowling ball, because it has more mass and therefore more inertia
D
the bowling ball, because it has less mass and therefore less inertia
Explanation
The bowling ball requires more force to get rolling because it has more mass than the basketball. Greater mass means greater inertia, so the bowling ball resists a change in motion more. Choice C correctly connects the bowling ball’s greater mass with greater inertia.
