Momentum is Mass * Velocity, therefore it is Kg*m/s Impulse is Force * Time, therefore it is N*s
By Newton's 2nd law, F=ma. Force(N) is equal to kg*m/s^2
By substitution, (kg*m/s^2)*s = kg*m/s

That would probably depend on the specific situation; there are several equations that involve momentum. Two important equations are: 1) Conservation of momentum: m2 = m1 (i.e., total momentum after some event, such as an impact, is the same as total momentum before the event) 2) The definition of momentum: p = mv (momentum, which is usually written as "p", is mass times velocity) cw: Impulse (Force X time) is equal to the change in momentum.
yes the momentum of it is the same because P initial = P final ALWAYS!
The same as the units you started with.
First of all ... I think you're talking about either the magnitude of the momentum, or the magnitudeof the velocity, not the magnitude of the objects.Now ... you're obviously skating around the subject of vectors here, recognizing that both thevelocity and the momentum are vector quantities.If, as you say, the two objects have " ... the same momentum ... ", then you're saying that theirmomentum vectors are equal. If so, then you'd have to say that yes, since the momentum vectorsare equal, the momentum vectors and the velocity vectors must all have the same direction.But if the two momenta only have equal magnitudes, then they ... and the velocities ... can be inany two directions, not necessarily related.
Momentum is a function of velocity and mass, therefore, assuming a "large" bus has more mass than a "small" car the bus would have more momentum since the velocities are the same.
