For the first part please include the signs >,<,= Thank you Shown below are six objects...
Torque and Angular Acceleration Learning Goal: To understand and apply the formula τ= Iα to rigid objects rotating about a fixed axis. To find the acceleration a of a particle of mass m, we use Newton's second law. Fnet =ma, where Fnet is the net force acting on the particle. To find the angular acceleration a of a rigid object rotating about a fixed axis, we can use a similar formula: Tnet = Ia, where Tnet=∑T is the net torque acting on the object...
