Torque, Energy, Rolling
... Torque, t, is the tendency of a force to rotate an object about some axis Let F be a force acting on an object, and let r be a position vector from a rotational center to the point of application of the force, with F perpendicular to r. The magnitude of the torque is given by ...

A batter has better control with a straight stick than a baseball bat because the radius of gyration is closer to the batter’s hands. But, since the radius of gyration is closer to the batter’s hands on a straight stick than ...

Example 22-2 An Electric Field Due to a Changing Magnetic Field
... Our results show that the more rapid the change in magnetic field, the greater the magnitude of the electric field that is induced. If a circular loop of conducting wire were placed along the circular path of diameter 3.50 cm, a current would be generated so as to produce a magnetic field that woul ...
