For example: It is rather rare in practice to have to calculate the impulse of a force from its time variation. 4.2.2 Definition of the linear momentum of a particle The linear momentum of a particle ...

For more info use the impulse and momentum page of the Mechanics section. The momentum, $p$, of a body of mass $m$ which is moving with a velocity $v$ is $p = m ...

It is hit by a squash racquet which applies a force for 4 milliseconds, so that the ball leaves the racquet at 8.4 ms-1 moving from right to left. Impulse-momentum can be used to calculate the ...

When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum.
