Question

what is the dimension of angular impulse​

Answer 1

Angular impulse is defined as the product of  torque and time for which it acts.

Mathematically,

Angular impulse = Torque X Time.

Dimensional Formula of Torque = M1L2T-2

Dimensional Formula of Time = M0L0T1

Putting these values in the given equation we get,

Dimensional Formula of Angular impulse = M1L2T-1

SI Unit of Angular impulse is Kg m2s-1

Answer 2

The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram meter per second (kg⋅m/s).
