Understand perfectly inelastic collisions through a simple clay ball example. This video explains how momentum is conserved while kinetic energy is not, helping you visualize what happens when objects ...

A red and a blue snooker ball both have a mass of 160 g. They collide with speeds and directions as shown in this diagram. The following steps show you how to calculate the velocity of the red ball ...

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 ...
