A rocket moves forward by expelling high-speed gases out of its engines, in accordance with Newton's third law of motion. As the gases are ejected downward, an equal and opposite reaction force propels the rocket forward. This principle is known as action and reaction.
A rocket has to overcome the force of gravity in order to move skyward. This force pulls the rocket downward and needs to be overcome by the thrust generated by the rocket's engines in order to achieve lift-off.
Propulsion is the force that moves an object forward. It is the result of applying force to the object in the opposite direction it needs to move. For example, in a rocket, propulsion is generated by expelling propellant gases backwards, causing the rocket to move forward.
A rocket is propelled by the force of the expanding gases produced when fuel is burned in the combustion chamber. This force pushes the exhaust gases out of the rocket's nozzle in one direction, causing the rocket to move in the opposite direction as described by Newton's third law of motion.
Newton's Third Law of Motion: For every action there is an equal and opposite reaction. Understand that it is not the exhaust that makes a rocket or reaction motor work, but the force that is applied where no resistance exists. A rocket can be compared to a balloon. The inflated balloon has pressure in all directions, and so does not move. Opening the neck means that there is no pressure at the neck end, and the pressure at the opposite side of the balloon makes it move forward.
Thrust, and lots of it. for about $25 bucks @ you're locale hobby store, you can buy a model rocket kit that uses the same basic idea's as nasa's
It is not the action but the reaction force that makes a rocket lift up. The action force is the force released when the rocket fuel burns. This action force acts on the surface/ground and according to Newton's Third Law [For each and every action, there is an equal and opposite reaction], a reaction force acts towards the rocket hence giving it a lift.

When a force makes an object move, work is done.
The natural force wind makes the leaves plants move.

Friction makes it harder to move things.

There are two forces acting on a water rocket. The thrust which the force that is given to the water rocket to make it move, and the other one is the gravity.
true.due to newton's 3rd law when the gases push against d ground,the force exerted makes it move ahead.
