Question

Anika asks Eva to roll a basketball and then a bowling ball to her. Which requires more force to roll, and why?

Answer 1

It's easy to roll the the basket ball than bowling ball

It is because bowling ball is solid spherical ball which will have less moment of inertia

its moment of inertia is given as

$I = \frac{2}{5}mR^2$

While for the hollow ball like basketball we know that moment of inertia is given as

$I' = \frac{2}{3}mR^2$

so here we can see for the same mass if we take basketball then its moment of inertia is more so it is easy to roll basket ball then to roll bowling ball.

So it is easy to roll basket ball then rolling ball

Answer 2

Answer:

the bowling ball, because it has more mass and therefore more inertia
