This physics video covers a tutorial on the conservation of momentum for a system of particles in 2D Cartesian coordinates. It explains when momentum is conserved and when it is not. Generally, momentum is conserved when there is no net external force acting on the system. The conservation of momentum is commonly applied to solve for the velocities of particles involved in in elastic and inelastic collisions. Note that the internal forces in the system cancel each other out by Newton's third law, so momentum is not conserved for a single particle subjected to an impulse.
