A rocket launching into space is a classic example of Newton's Third Law. The other two apply, but it is because of Newton's Third law that a rocket can launch into space. When the rocket engines fire, large amounts of gas escapes from the nozzle at high speed. This requires signifigant force to launch these gasses. Since Newton's Third Law states that for every action, there is an equal and opposite reaction, we know that the gas pushes back up on the rocket with just as much force as the rocket pushes down on the gas. This force launches the rocket into space.
It's also shows Newtons law number 1.
"An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
If you don't ignite the rocket motor (The unbalanced force), nothing happens.
The rocket pushes into the ground at -9.81 metres per second and the Earth Pushes up at +9.81 metres per second. When you ignite the rocket this stable force becomes unbalanced by the thrust produced by the rocket motor and if the motor thrust exceeds the mass of the rocket the rocket will rise.
And number 2...
"Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object)."
Fuel, mass and thrust falls into this category. The heavier the rocket is the more thust you need the bigger or more efficient the engine needs to be and the more fuel you will need to provide the thrust.
And number three you already know about but for completeness.
"For every action there is an equal and opposite re-action."
The rocket ejects high speed gases down, therefore the rocket goes up.
Newton's third law of motion is key to rocket launch.
Newton's third law explains the motion of a rocket in space.
Newton's Third law
Newton's Third Law. Equivalent to Conservation of Momentum. By Newton's Third Law, if the gas is pushed out of the rocket, the gas pushes the rocket back, in the opposite direction.
Newton's Third Law: "For every action there is an equal and opposite reaction."
Currently any satellite must be launched on a rocket to reach space, though ideas for non-rocket launch exist.
A space suit and a rocket and space man food!
If we start from newtons third law, we can get the idea of action and reaction is equal and opposite It is its' fuel ejection that enables the rocket to fly forward. P=MV But here mass is decreasing due to the consumption of fuel thus, we are now flying at P= (M-m)V WHERE M grater than (M-m) hence the rocket clearly is moving at a constantly decreasing mass with constant velocity. therefore it clearly accelerates as time goes.

newtons 3rd law
the rocket works on newtons law, which states that every action has an equal reaction in opposite direction. the rocket releases a jet of hot gases which propels it to the space:)
it can fly because the fire that comes out of the back of the rocket is its thrust.So when the fire comes out the back it causes the rocket to thrust forward.Remember the fire comes out with a lot of force thats why the rocket is able to fly because of the thrust. The body of the rocket is a device that can stay in space and float in there which allows the rocket to stay in space. The fire thrusts the rocket up but only to get out of earths atmosphere because earth has gravity space doesn't. In space the rocket does the rest of the work which is floating in a place without gravity. hope this helped!

they lunches off with a rocket first then orbits a planet. Then shoots off on to the planet. after witch, the rocket blows apart back to earth.
a rocket powers the space station into orbit
In 1969, the first rocket went to the moon. The name of the rocket that propelled them into space was the Saturn V rocket.
a rocket powers the space station into orbit
a rocket is how people get into and get stuff into space
the pressure from the the rocket's fuel thingy makes the rocket go up. pretty soon, the rocket is in space.
