first law
1st. The rocket sets still until a force, burning fuel, causes a change in motion. 2nd. F=ma The force of the burning fuel causes an acceleration of the rocket. 3rd. Action/reaction. The action of hot burning gases leaving the rocket causes a reaction, which is the motion of the rocket in the opposite direction. Note: The exhaust does not need to hit the ground to cause the reaction. A rocket engine ignited in outer space will cause a change in the motion of the rocket.
I think this is a question about how a rocket motor works. If you burn high explosive fuel in a closed box and the box is strong enough, the box won't move because the forces on all the walls balance each other out in all directions. But if you open a hole in one wall, then suddenly there is imbalance, and the unbalanced force on the wall opposite the hole will force the box to accelerate in that direction. A rocket motor is exactly such a box, which is continually fed with high explosive fuel.
If a rocket pushes the burning gases towards the Earth, then - according to Newton's Third Law - those same gases push the rocket away from Earth.
The same way a chemical rocket works. Instead of burning fuel to create a force to propel the rocket, stored pressure released in one direction propels the rocket. Both chemical and pressure rockets make use of Newton's Third Law of Motion, for every action there is an equal and opposite reaction.
The function of a recovery system on a rocket is to allow it to gently return to the earth. This allows the equipment to be reused in later launches to cut down on costs and down time.
As long as the thrust is more than the weight of the rocket (toy or otherwise) the rocket will accelerate. When the thrust matches the weight, the rocket will cruise. When the thrust is less then the rocket will slow.

Yes, he was very famous, although he did not invent the rocket: he build the primitive spaceship: a space rocket.
you need to put power-ups in the rocket to make it fly
It takes a rocket only 8 minutes to accelerate to a speed of 15,000 miles per hour
