Jan 14, 2023 at 21:28 | comment | added | John Darby | Comment about force seems wrong. Any net external force causes acceleration of CM. Torque depends on point about which it is evaluated. For example, ball rolling down incline. Torque from friction with respect to CM is not zero, torque due to friction with respect to point on incline is zero.

Jan 14, 2023 at 3:17 | comment | added | FourierFlux | I see, for some reason one of my books talked about the line of action directed towards the COM is the only component which would impart linear acceleration and the perpendicular component would only impart torque | |
