Law of Impulse Conservation in Multiple Elastic Collisions on a Demonstration Track with a 4-4 Counter by PHYWE

The impulse of a force acting on an object is defined as the change in the object's impulse caused by the force F over a brief period of time t. The impulse of force I is calculated as the product of force and time. This holds true even in multiple collisions, provided there's no friction and the collision is elastic.
