How does the first and third law of motion apply to a rocket launching?

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.


What is the pulling or pushing force from a spaceship?

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.


How does Newton's third law explain how a rocket accelerates?

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.


How does a pressure rocket work?

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.


What is the function of recovery system a rocket?

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.

How could a toy rocket accelerate after takeoff?

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.
