Now that we know what momentum is, let's learn about the conservation of momentum and collisions.
Similar to the law of conservation of energy, this becomes a useful tool for studying and predicting the motion of objects. If we know the total momentum of a system of objects at any moment in time, we know that value will be the same at another moment in time.
The most common scenario where we apply the conservation of momentum is a collision. A collision is when 2 or more objects come into contact with each other, like 2 cars colliding. But we can also consider scenarios like explosions, where objects or pieces of an object start together and then fly apart. We'll learn about several types of events including elastic collisions, inelastic collisions, perfectly inelastic collisions and explosions.
