Conservation of Momentum Summary

The video tutorial explains the concept of momentum conservation in a system of snooker balls. It highlights the difficulty in determining individual velocities post-collision but emphasizes that the total momentum remains constant if no external forces are present. The tutorial also discusses how external forces, like a ball hitting the table's side, can disrupt momentum conservation in a specific direction.

What is the significance of the total momentum of a system before and after a collision?

How can the momentum of individual particles be expressed mathematically before and after a collision?

Explain the conditions under which the conservation of momentum applies.

Describe the effect of a ball colliding with the side of a table on the momentum of the system.

What happens to the conservation of momentum if an external force acts on the system?
