We know that both cars and rockets need fuel. But, the mechanism with which cars and rockets move is slightly different. In a car, the fuel is burned to make the shaft rotate, which in turn make the wheels rotate. As the wheels rotate, the car moves.

But, how does a rocket move? There are no wheels. In fact, a rocket doesn't have moving parts. But, it can move much faster than a car! Let's learn how this is possible.
