... A student sits on a rotating stool holding two weights, each of mass 5.00 kg and approximated as point masses. When his arms are extended horizontally, the weights are 0.850 m from the axis of rotation and the student rotates with an angular speed of 2.00 rad/s. The moment of inertia of the student ...

Friction Factors - OUHSDPhysicsCollaboration
... We are constantly aware of the frictional force that opposes the motion of one surface in contact with another. When there is a sheet of ice on a sidewalk, friction is reduced, and it is difficult to walk. The lack of friction is an inconvenience. However, machines are lubricated to reduce friction ...
