What are physical constraints?

Physical constraints are rules that things have to follow because they're made of stuff we can touch and feel.

Imagine you’re playing with building blocks. Each block has size, and they can only stack so high before they fall over. That’s a physical constraint, it's like the blocks whispering, “Don’t go too tall or I’ll tumble!”

Think of a slide. You can climb up the ladder, but you can't just jump from the top to the bottom, that might hurt! The slide has its own rules based on how it's built and what it’s made of.

Your body is like a team of builders. When you run, your legs have to move in certain ways because of how muscles and bones work together. If you tried to walk like a kangaroo, you might trip, that's also a physical constraint!

So, physical constraints are just the rules that things follow based on what they’re made of, like blocks on a playground or your body when you're playing!
