Explore collision physics by learning how to determine elasticity in train car crashes! This video breaks down the concepts of elastic and inelastic collisions, momentum conservation, and energy ...

For example, an elephant has no momentum when it is standing still. When it begins to walk, it will have momentum in the same direction as it is travelling. The faster the elephant walks, the larger ...

Here is a worked example. Two railway carriages collide and move off together. Carriage A has a mass of 12,000 kg and moves at 5 m/s before the collision. Carriage B has a mass of 8,000 kg and is ...
