What are nuclear fusion processes?

Nuclear fusion is when tiny particles inside atoms come together and make something bigger, like a tiny explosion that creates energy.

Imagine you have two super small balls, each made of stuff from the sun. When they bump into each other really fast, they stick together and create a new ball, and poof! some energy is released, just like when you let go of a balloon and it zooms off!

Think of nuclear fusion like making a sandwich. You have two pieces of bread (the small balls) that are really close to each other. When they meet in the middle, squish!, they form a bigger sandwich (a new atom), and some energy is released, just like when you press down on a spring and it pushes back.

This happens all the time inside the sun! It's like a giant kitchen where millions of tiny balls are crashing together every second. That’s why the sun is so bright and warm, it's making energy by fusing those little particles together, just like you make a sandwich at lunchtime.
