Momentum: The quantity of motion of a moving body, and is a conserved quantity.
Impulse: the change in momentum
To calculate momentum we use the equation p = m*v
To calculate impulse we use can use average Force * T = J
this means that on a force vs time graph impulse is defined by the area under the graph.

Additionally impulse can also be found by using the equation J = mf * vf - mi * vi which just compares the initial momentum to the final momentum
One of the most important examples of momentum occuring is during collisions.
there are two main types of collision which occur these are inelastic and elastic.
Inelastic collision: Collision where the objects collide stick to each other after the collision
An example of an inelastic collision is the carts shown below. you can tell its inelastic as the carts stick to each other after colliding.

An example of an inelastic collision is the carts shown below. you can tell its inelastic as the carts stick to each other after colliding.
Elastic collision: Collison where the objects bounce off each other and do not stick together
An example of an elastic collision is the carts shown below. We know that its elastic due to how the carts bounce of each other and dont stay together after the collision.
