... If all forces are applied at the center of mass, they produce no torque; however, a force acting at a point on the body other than the center of mass will also cause a torque. To frnd a torque about a coordinate frame's axes due to a force f (f,lrl) applied at point p (x,y,z) (both defrned relative ...

... Note that we have taken the positive square root, implying that dθ / dt ≥ 0 . This clearly cannot always be the case, and we should change the sign of the square root every time the pendulum’s direction of motion changes. For our purposes, this is not an issue. If we wished to find an explicit form ...
