What is collision?

A collision is when two things bump into each other and change how they’re moving.

Like Bumping Into a Friend at Playtime

Imagine you're playing tag in the park, and you run right into your friend. Both of you stop suddenly, maybe even fall over, that’s a collision! Just like you and your friend, when two things hit each other, they can change direction or speed.

Like Bumper Cars at the Fair

Think about bumper cars at the fair. When one car hits another, both cars move in new directions. That’s also a collision, it's just happening on a bigger scale and with more fun!

In both cases, something happens because of a bump, not magic, just real-life movement changing from one moment to the next!
