My textbook says any torques associated with the internal forces acting in a system of particles are zero and therefore net external torque = total angular momentum/ time
First of all, what is net external torque? Is it just net torque? Is there a thing called internal torque?
Second, why is any torques associated with the internal forces acting in a system of particles are zero?
Thanks!
