A 1 kilogram mouse walks across a road at a velocity of 0.01 m/sec. What is the mouse's momentum?

Answer 1

The momentum of an object is given by the product of its mass and velocity.

In this case, the mass of the mouse is 1 kilogram and its velocity is 0.01 m/sec.

So, the momentum of the mouse is:

Momentum = Mass × Velocity
= 1 kg × 0.01 m/sec
= 0.01 kg⋅m/sec

Answer 2

0.01 kg m/s is the MAGNITUDE of the momentum, not the momentum

Answer 3

You're correct. The magnitude of the momentum is 0.01 kg m/s. However, momentum is a vector quantity that also has direction. To fully describe the momentum of the mouse, we need to specify its direction as well.
