Imagine you're on a really fast skateboard, and you push off the ground with all your might. That’s like what a rocket does, it pushes itself up by throwing things out super fast! A rocket uses engines to shoot fuel backward at high speed, which makes it move forward. This is called thrust. If it goes fast enough, about 25,000 km/h, it can escape Earth's gravity and travel into space.
Examples
- A toy rocket uses a balloon filled with air, when you let the air out quickly, it zooms forward.
- Pushing your friend on a swing gives them more speed each time, helping them go higher.
- A fire truck’s siren sounds different as it moves toward and away from you, that's how sound behaves in motion.
