Disintegration theorem

The disintegration theorem helps us understand how things break apart. Imagine you have a block of wood, like a log. The disintegration theorem tells us that if you drop it from a high place, it will break apart into smaller pieces. We use the same idea to understand how other things break down into smaller parts. For example, if you have a big pile of sand, the disintegration theorem says that when you drop it, it will break apart into lots of small pieces. The same thing happens when we drop a rock or a glass bottle. We can use the disintegration theorem to help find out how things break down and why.
