A collision occurs when 2 objects "bump into" each other. In terms of physics, we often talk about collisions as being elastic or inelastic. Here are some examples to illustrate further.
Elastic collisions - Imagine 2 tennis balls being thrown at each other. When they bump together, what happens? Each bounces back without much speed loss. This is because the material that tennis balls are made out of are elastic. Energy is conserved in these collisions.
Inelastic collisions - Imagine taking out an egg from your fridge and throwing it at the ground. Do you expect the egg to bounce back up? Probably not. This is because the collision has caused the energy that drove the egg to the ground to be absorbed by the ground, upon collision. Of course, part of that energy will be converted to the sound you hear -- splat!
Hope this helps!
