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)
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.
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.
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.
Why is angular momentum NOT measured in kg m2 rad s-1?
For the same reason it's not measured in buckets of rotten fish: because those would not be the correct units. Angular momentum is the cross product of the linear momentum and the position vector relative to the center of rotation. If you do a dimensional analysis, you'll see that the proper units are joule-seconds.

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.
Is impulse the same as momentum true or false?
Impulse is a change of momentum (delta p).

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

Show that impulse units are the same as momentum units?
Momentum is Mass * Velocity, therefore it is Kg*m/s Impulse is Force * Time, therefore it is N*sBy Newton's 2nd law, F=ma. Force(N) is equal to kg*m/s^2By substitution, (kg*m/s^2)*s = kg*m/s

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.
