What are the types of propulsion?

There are different types of propulsion that help things move, just like how you push a toy car or ride a bike.

Imagine you're playing with your favorite toy car. If you give it a little push, it starts moving, that's like direct propulsion. It’s what happens when something is pushed right away to get it going. Rockets use this kind of push too, but they do it with fire and gas instead of your hands!

Now think about a toy train. If the engine pulls the whole train along the track, that's pull propulsion. It’s like when you pull a wagon, you're using your strength to move something else. Some vehicles use this kind of power too.

Sometimes things move because they have stored energy, just like a spring in a toy. If you wind up a toy and let it go, it moves all by itself, that’s stored energy propulsion. It's like when you stretch a rubber band and then let it snap back!

Each kind of propulsion helps different things move, from your favorite toys to big rockets flying into space!
