During a collision between two objects, the interactions between the objects can be very complicated, and may consist of both conservative and nonconservative forces, but as long as the objects are not affected by any external forces, their total momentum is conserved. Impulse is a vector the impulse is equal to the change in momentum if the time is short, the force can be quite large. Most calculations of impulse are rather straightforward.

Momentum and impulse analyse impulse, and momentum transfer. For a system of several objects, the momentum of the system is the vector sum of the momenta of all the objects. The impulse tells us that we can get the same change in momentum with a large force acting for a short time, or a small force acting for a longer time.

In fact, newton actually wrote his second law n2l in terms of linear momentum.
Conservation of momentum is particularly useful for collisions. The linear momentum p of an object of mass mmoving with a velocity v is defined to be the product of the mass and velocity. For a perfectly inelastic collision, the total momentum is conserved but the total kinetic energy is not conserved during the collision.

Momentum, energy and collisions the collision of two carts on a track can be described in terms of momentum conservation and, in some cases, energy conservation. If there is no net external force experienced by the system of two carts, then we expect the total momentum of the system to be conserved.
