Bicycle in motion


Taking the formula for momentum to be #p=mv# this is the mass multiplied by the velocity.

Although the semi truck certainly has a larger mass, it is not in motion and therefore does not have any momentum.

The bicycle however has both mass and velocity and therefore has the larger momentum of the pair.
