When comparing the momentum of 2 moving objects, which of the following is correct?

• the object with the higher velocity will have less momentum if the masses are equal

• the more massive object will have less momentum if its velocity is greater.

• the less massive object will have less momentum if the velocities are the same

• the more massive object will have less momentum if the velocities are the same
