WebMay 1, 2024 · This torque reduces the ball's angilar momentum and thus the ball comes to rest. Just in case, if the friction is absent on the inclined plane, then the ball's ω will not change when it reaches at the top on the inclined plane. Onky the velocity will change. Thus in the center of mass frame, the angular momentum ( I ω) will be conserved.
