What is strain?

Strain is what happens to something when you push or pull on it, just like stretching a rubber band.

Imagine you have a slinky. When you hold both ends and gently pull them apart, the slinky gets longer. That change in length is called strain. It’s like how your arms feel when you stretch during playtime, they get longer, and that's strain working!

Strain happens because of something called force. When you push or pull on an object, that force causes it to change shape or size. The more force you use, the more strain you create.

Think about playing with a bungee cord. At first, it’s short and tight. But when you jump, the bungee cord stretches, that's strain in action! It changes from being short to long because of the pull from your jump.

So next time you stretch a band, squish a playdough ball, or even jump on a trampoline, remember: you're making strain happen all around you! Strain is what happens to something when you push or pull on it, just like stretching a rubber band.
