What are collision processes?

Collision processes are when things bump into each other and change what they're doing.

Imagine you're playing with marbles on a table. When one marble bumps into another, something happens, maybe the first marble stops, or it moves in a new direction, or both marbles start moving. That's like a collision process!

Think of it like this: you're riding your bike and suddenly someone else's bike hits yours. You both might swerve or stop, that’s a collision too! The way the bikes move after the crash depends on how fast they were going and how heavy they are.

Sometimes, when things collide, they stick together, like when two clay balls hit each other and become one big ball. Other times, they just bounce off, like when two rubber balls hit and go their separate ways. These different results help scientists understand how collision processes work in the real world!
