gravity – Would a light or a heavy ball roll fastest down a slope? – Physics Stack Exchange

Sunday, January 29th, 2017

http://physics.stackexchange.com/questions/19552/would-a-light-or-a-heavy-ball-roll-fastest-down-a-slope

QT:{{”

both balls should have same acceleration (and therefore same velocity and displacement).

However, if there’s air drag, their acceleration depends on the radius and the mass of the ball, so not enough information is given for this case. If the balls are of the same material (same density ρρ), the larger one comes down faster than the smaller one.
