What are particle interactions?

Particle interactions are when tiny building blocks called particles bump into each other and change how they move or behave.

Imagine you're playing with toy balls in a bouncy castle. When one ball hits another, it might push the other one away or make it go faster, that’s like what happens to particles!

Think of particle interactions as a party where all the guests (the particles) are having fun and bumping into each other.

• If two balls collide, they might switch places or move in new directions.
• Sometimes, one ball might get extra energy from another, like when you jump on a trampoline and bounce higher!

These tiny parties happen everywhere, in your body, in the air, even inside the sun! Scientists watch these little collisions to learn how everything around us works.
