Question

Expression torque in the term of m.i ? Also give expression of conservation of angular momentum

Answer 1

Answer:

When a torque is applied to an object it begins to rotate with an acceleration inversely proportional to its moment of inertia. This relation can be thought of as Newton's Second Law for rotation. The moment of inertia is the rotational mass and the torque is rotational force.

The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero. ... →L=constant L → = constant (when net τ=0). This is an expression for the law of conservation of angular momentum.
