Question

dimention angular momentum​

Answer 1

Angular momentum is the moment of linear momentum.

The dimension of angular momentum is:

[L²MT-¹]

Answer 2

Angular momentum can also be considered as moment of momentum.That means momentum x perpendicular distance from the point about which body’s momentum is defined. Thus momentum=mass x velocity, therefore units are MLT^-1 and hence angular momentum will have units as MLT^-1 x L=ML^2T^-1
