What is the equation in solving for momentum?
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.
When a toy truck collides into a toy car the momentum of is the same before and after the collision?
yes the momentum of it is the same because P initial = P final ALWAYS!
What are units for circumference of a circle?
The same as the units you started with.
If two objects have the same momentum do their magnitudes necessarily have the same directions?
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.
Is the momentum of a large bus greater than less than that of a small car traveling at the same speed?
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.
