Magnetic Forces

Magnetic Forces. Magnetic Forces. Charged particles experience an electric force when in an electric field regardless of whether they are moving or not moving There is another force that charged particles can experience even in the absence of an electric field but only when they are motion

L-10 torque and rotational inertia

L-10 torque and rotational inertia. We consider the rotation of rigid bodies . A rigid body is an extended object in which the mass is distributed spatially. Where should a force be applied to make it rotate (spin)? The same force applied at different locations produces different results.
