rockets are propelled by using a theory of equal and opposite reactions as some of them have already mentioned. but in space , if it is rotating around earth, it continuously keeps faaling towards earth due to earth's gravitational pull but every time the earth seems to slip from below and it never actually falls and thus keeps rotating.

All a rocket need to move through space is anything to push or pull it. There is no resistance in space, or should I say empty space. Resistance would be caused by anything such as the earths atmoshere. So u could start the rocket go 5 mph and it would constantly pick up speed without any extra effort just a constant 5 mph burst

force, counter force.
They ignite the fuel and the thrust (pounds per square inch) comes out the end of the rocket, pushing it forward. I know, what is there to push against, well, alot. The fact that the rocket is thrusting at all is what matters, it doesn't need a surface to push against. It exerts pressure, the rocket body moves in dynamic proportion.

Well, for this we have to go back to Sir Isaac Newton.
“For every action, there is an equal but opposite reaction”
A rocket’s exhaust is shot out at huge velocities. That is the action. As this is done, the craft is pushed forward. This is the reaction.

Get yourself up into outer space (Wear a spacesuit) and grab a rock, and fling it away from you. You will move with the equal amount of force away from the rock that you flung away from you. Newton described this law of motion many years ago, it conserve's energy. A rocket fling's stuff away from itself so it can move in the direction it chooses. Hope this help's PEACE, TJ

for every action (propellent out the back) there is an equal and opposite reaction (rocket goes forward)

they usualy have a fule tank that is really big and gets them out of the atmosphere. then they drop it into the ocean. in space they use small amounts of fuel to direct them. in space if you move one way you keep going thatway forever at the same speed. im pretty sure

Usually hot gas expanding and pushing against the craft.

expanding gas pushes on inside of rocket.
some gas goes out back instead of pushing on rocket.
rocket receives net force in forward direction.
rocket go fast.
