Rotational Motion
... changes with time determines the angular velocity ω. The direction of angular velocity is either clockwise or counterclockwise. How quickly the angular velocity changes determines the angular acceleration α. The linear velocity v and linear acceleration also v depend on the radius of rotation, which ...

... colliding objects as long as there are no outside forces. For example, if someone holds down the darker ball in the collision shown above, it will not move. In that case, the momentum of the lighter ball would be transferred to the person holding the ball. The person is exerting an outside force. Th ...

... We might next ask ourselves: What are the operations of addition and scalar multiplication on V /U ? Surely these operations should somehow be induced by the corresponding operations from V . Indeed, this is the case, and it is natural to define addition and scalar multiplication in the following ma ...

7.2 Angular Momentum
... momentum of the system does not change. Skaters, gymnasts, dancers, and divers use conservation of angular momentum. For example, a diver changes from a pike position to an extended position at the end of a flip. This extension of mass away from the center of rotation increases the diver’s moment of ...
