# Does more angular monentum mean faster spin?

• B
If a top has angular momentum of 12 units and the earth has angular momentum of 100. Does this mean that Earth is spinning faster than the top since it has more angular momentum? The answer is there at the back of my head but cant articulate it.

A.T.
No. Angular velocity tells you what spins faster.

No. Angular momentum ( its magnitude) is the product of moment of inertia and the angular velocity. In your case the rotational inertia of the earth and the top aren't equal, so you can't make the conclusion as you did.
