8 All bodies dropped together fall to the ground in the same amount of time. But if
two spheres roll down an inclined plane, one may take more time than the other.
Explain why.

When a body drops through open space, gravity of the Earth pulls it towards to ground at 9.8 Metres per second, per second. This is a constant. The only force acting against it would be air resistance.
When a body rolls down an inclined plane, there is the addition resistive force of Friction to overcome, and this could be variable, resulting in the difference.

Because the spheres are different diameters and the larger one rolls farther than the smaller one in the same amount of time. Or is it the other way around? I think it might be the other way but I do know for sure that it is because they are different sizes

(A) the extra effective one would have extra rotational inertia and as a effect no longer start up rolling as at as quickly as. (B) A decrease CG ability that the deliver is extra solid to capsize (turn over) in tough seas. yet, via doing this, they stress the hull to think of a narrower bypass area so the two the water friction and the quantity of draft (water required below the vessel) are extra effective.

Their moments of inertia are different. The object with the the higher moment of inertia will resist being rotated more than the other one and will won't roll as fast.
