... impulse to the floor when it hits? Both objects reach the same speed at the floor. However, while the beanbag comes to rest on the floor, the ball bounces back up with nearly the same speed as it hit. Thus, the change in momentum for the ball is greater, because of the rebound. The impulse delivered ...

Rotational Dynamics
... In the same way that counterclockwise rotation produces positive angular displacement, it also results in positive angular velocity. If an object’s angular velocity is ω, then the linear velocity of a point at distance, r, from the axis of rotation is given by v = rω. The speed at which an object on ...
