Momentum(p) = m*v.
p=f/a*v; since f=ma.
f=p/a*v; since a=v/t;.
f=p*t;.
Since time is constant, when we apply same force the momentum only changes.
p=f/a*v; since f=ma.
f=p/a*v; since a=v/t;.
f=p*t;.
Since time is constant, when we apply same force the momentum only changes.

Force = rate of change in momentum over time.
f= p/t.
Therefore p=f*t as per newton second law of motion states.
f= p/t.
Therefore p=f*t as per newton second law of motion states.

According to newtons second law force is rate of change of momentum with time. So F=dp/dt.
We can write,
dp=f.dt.
So same force act for same time.
Hence momentum is same.
We can write,
dp=f.dt.
So same force act for same time.
Hence momentum is same.

Applied force is same.
Momentum=Mass*Velocity.
1st body velocity is high as mass is low.
2nd body velocity is low as mass is high.
Momentum=Mass*Velocity.
1st body velocity is high as mass is low.
2nd body velocity is low as mass is high.

According to Newton's 2nd law: Rate of change of momentum = Force.

According to the newton second law the rate of change of momentum is equal to force.

We know that.
F = dp/dt.
dp = F*dt (where * is used here for multiplication).
Since here force and time is same so the change in momentum will be the same.
F = dp/dt.
dp = F*dt (where * is used here for multiplication).
Since here force and time is same so the change in momentum will be the same.

Momentum is the right answer.
We know f = ma.
Here initial velocity u is 0.
Therefore p = f*t [ma*t = m*v-0/t*t = mv].
As force and time is constant both have same momentum.
We know f = ma.
Here initial velocity u is 0.
Therefore p = f*t [ma*t = m*v-0/t*t = mv].
As force and time is constant both have same momentum.

Momentum is the more force got very few second is called momentum.

This is according to the newton 2nd law of motion.
