Many of my students make a widespread mistake of taking friction value as f= μ N. Where μ = coefficient of friction and N =Normal Reaction.
So is it incorrect? The answer is not exactly. With that,...

It states that if net torque acting on an isolated system is zero, the angular momentum remains conserved.
Since Torque is equal to the rate of change of angular momentum so when torque is zero,
dL/dt=0
So,...
