Tag: To understand and apply the formula τ =Iɑ to rigid objects rotating about a fixed axis.

Learning Goal: To understand and apply the formula τ =Iɑ to rigid objects rotating about a fixed axis. To find the acceleration ɑ of a particle of mass m, we use Newton’s second law: , where  is the net force acting on the particle. To find the angular acceleration ɑ of a rigid object rotating about a fixed axis, we can use a similar formula: τnet…
