What are time-independent interactions?

Time-independent interactions are when things affect each other without needing time to pass, it’s like a constant friendship that doesn’t change.

Imagine you have two toy cars on a track. If they always push each other the same way, no matter how fast or slow they go, that's time-independent. It's like having a best friend who always gives you the same number of stickers every day, no need to count or wait for a special moment.

Think about glue. When you stick two pieces of paper together with glue, they stay stuck forever (or until someone tears them apart). That's time-independent too! The glue doesn’t care how long the papers are together, it just keeps holding them in place.

Or think about a friend who always shares their snack with you, every day, no matter what. They don’t need to wait for lunchtime or a special event, they just share because that's how they're friends. That kind of friendship is time-independent too!

So, time-independent interactions are like having a best friend, glue, or toy cars that always behave the same way, without needing time to make it happen!
