What is Speed | Science for Kids?

Speed is how fast something moves from one place to another.

Imagine you and your friend are racing on your bikes. If you zoom past your friend really quickly, you have more speed than they do. Speed is like the “go-go power” of a toy car, the faster it goes, the more speed it has!

When something moves, it covers distance in a certain amount of time. Think about walking to the park. If you walk slowly, it takes longer, that means your speed is low. But if you run, you get there faster, that means your speed is higher!

Speed can be measured like this:

• If you go 10 meters in 5 seconds, your speed is 2 meters per second.
• That’s like taking two big steps every second!

Your mom might drive to work at a steady speed, while your dad might speed up and slow down, that’s why he gets there faster sometimes!

So, speed is just how quickly something moves from one place to another. It's like being the fastest runner in the class, you have the most speed!
