Explain why angular momentum is sometimes called ‘moment of momentum’. The answer is [angular momentum]=L [linear momentum]. Can someone explain this to me please because I don’t understand it.

Thanks

Well a ‘moment’ is a product of some physical quantity and the perpendicular distance from an axis.

Now note that:

Angular momentum = (displacement) x (linear momentum)

Where the RHS is clearly a moment of momentum (linear momentum is the physical quantity, and displacement is like our ‘distance’)
