Do marbles go further down a hill if the hill is steeper?

Answer 1

Yes, sometimes and no sometimes. In the case of rotating objects the more import value is moment of inertia. An object with a higher moment of inertia will accelerate slower (roll slower comparatively for any given time after release) down an inclined plane.

In the case where the marbles are of equal diameter and uniform (although different if one is to have more mass) density the heavier marble will roll slower down a slope.

For those interested in a short description followed by plenty of calculus.

Answer 2

Yes, marbles will go further down a steeper hill because gravity will exert a greater force on them, causing them to accelerate at a faster rate. This increased acceleration results in the marble covering more distance in a shorter amount of time.

Answer 3

yes because it has a greater potential energy to go down the steeper hill than it would will a less steep hill.
