Introduction to Momentum and Conservation of Momentum

The video tutorial covers the concept of momentum, its calculation, and its conservation. It begins by explaining momentum as a vector quantity, calculated as mass times velocity. The tutorial then explores momentum in systems with multiple objects, emphasizing the importance of direction. It illustrates the conservation of momentum through examples, including a collision between a locomotive and a truck, and an explosion where an object splits into fragments. The video demonstrates how total momentum before and after events remains constant in closed systems.

Describe the conservation of momentum in a closed system.

What happens to the total momentum before and after a collision between two objects?
