Rolling, Torque, and Angular Momentum
... between force and linear momentum for a single particle. There is also a close relationship between torque and angular momentum: Tnet = dl/dt The vector sums of all the torques acting on a particle is equal to the time rate of change in the angular momentum of that particle. The torques and angular ...
