Question

What does the time-rate of change of angular momentum indicate?

Answer 1

Explanation:

time-rate of change of angular momentum indicate the Torque.

Answer 2

Answer:

The rate of change of angular momentum indicates the torque.

Explanation:

Since we know the relation among angular momentum , linear momentum and position vector.

$L = r \times P$.......................(1)

Wher L = Angular momentum , r = position vector , P =linear momentum

Differentiating (1) equation with respect to t.

$\frac{dL}{dt} = r\times \frac{dP}{dt}$

We know that the rate of change of linear momentum yields force as per newton second law of motion.

$\frac{dL}{dt} = r\times F = Torque.$

So, the rate of change of angular momentum indicates the torque.
