Get Full SolutionsSummary of Chapter 8: Dynamics of Rotational Motion
In this chapter we will define a new physical quantity, torque, that describes the twisting or turning effort of a force. We’ll find that the net torque acting on a rigid body determines its angular acceleration, in the same way that the net force on a body determines its linear acceleration.
