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

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!
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.
What are units for circumference of a circle?
The same as the units you started with.
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.
Are momentum and impulse measured in the same units?
Yes. You can think of an impulse as of a transfer of momentum.
Different standard units of force and momentum and impulse?
Force = mass x acceleration = kg(m/s^2) or N Momentum = mass x change in velocity = kg(m/s) or Ns The units of impulse are the same as momentum's because impulse is just the change in momentum.
What could be described as impulse equals change in momentum?
Momentum = Mass x Velocity The change in momentum = (mass of the object x the end velocity) - (mass of the object x the beginning velocity)
Is impulse the same as momentum true or false?
Impulse is a change of momentum (delta p).
Does a moving object have impluse?
More or less. Actually, a moving object has momentum - defined as mass times velocity. The word "impulse" is used for transfer of momentum, for example, in a collision. It has the same units as momentum, but the use of the word "impulse" seems inappropriate in this context.
Why is it incorrect to say that impulse equals momentum?
Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement. Impulse= final momentum-initial momentum= mv - mv_0= Force * Time Where m is the mass and v is the velocity.
The statement 'Impulse is not the same as momentum' is?
True.
What is the unit of impulse in physics?
Same as the unit of momentum - an impulse is a transfer of momentum. Velocity x mass. Or the equivalent force x time.
Difference between impulse and momentum?
Impulse is another name for change in momentum.Both momentum and impulse have same unit( Ns or kgm/s) . Impulse is also defined as force acting for a time "t". so, Impulse=F*t
The impulse given to a ball with mass of 4 kg is 16 Nsec If the ball starts from rest what is its final velocity?
An impulse is simply a change of momentum, and momentum is defined as mass x velocity; so you just divide the momentum by the mass to get the velocity. Note about the units: newton x second is the same as kilogram x meter/second2.
What are the units associated with mass x velocity?
Momentum is defined as mass times velocity, and it requires units of mass times units of velocity. The SI unit is kilograms x meters / second. There is no special name for this combination of units. Impulse (force times time) has the same units.
What is the name for the duration in which a force is applied?
In kinematics the product of Force and Time is called the Impulse. It has the same dimensions as Momentum. Thus Force has dimensions [M][L][T-2], so Impulse has dimensions [M][L][T-1], which is the same as Momentum which is Mass x Velocity. So if you apply an impulse of value Ft to a body it causes a change in momentum MV2 - MV1.
