Conservation of Momentum in Collisions

The video tutorial explains the concept of momentum conservation, starting with the basic equations for calculating momentum and changes in momentum. It introduces Newton's Third Law and its application in momentum conservation, particularly in collisions. The tutorial provides examples involving trolleys to illustrate how momentum is conserved in different scenarios, including stationary and moving trolleys, trolleys moving in the same direction, and trolleys moving towards each other.

What does it mean for momentum to be conserved in a collision?

How do you calculate the velocity of two trolleys after they collide and stick together?

In the example of two trolleys moving towards each other, how is the momentum calculated?
