Faraday`s Law of Electromagnetic Induction - UTK-EECS
... Faraday’s Law of Electromagnetic Induction 1. If the flux linking a loop (or turn) varies as a function of time, a voltage is induced between its terminals. 2. The value of the induced voltage is proportional to the rate of change of flux The “-” sign indicates that the inducted E has a tendency to ...

lecture 21 torque
... The sign of torque is the same as the sign of angular acceleration it causes if it were the only torque acting in the system. If two or more torques act on a rigid object, the net torque is the sum of the torques with correct sign assigned to each torque. This is analogous to Newton’s 2nd law for li ...

Motion in Two Dimensions
... A net torque would produce an angular acceleration. An object spinning at a constant rate will accelerate if the mass is redistributed farther or closer to the axis of rotation. Rotational Inertia is the resistance of a rotating object to changes in its rotational velocity-- it depends on mass, dist ...
