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.
Newton's first law of motion was the law of inertia. When an object is in motion, it stays in motion. When an object is in rest, it stays in rest.

motion
Newton's first law, which states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
I have never seen it called that before. Perhaps whoever used this name meant that it is a law that applies in our real world - as opposed to any other law which you might make up, but which doesn't apply in our world.
it was the first rocket launching station in India
ROBERT HUTCHING GODDARDOn 6th March 1926 he got succeeded in launching its first liquid propellant rocket.
first stage: engine of the rocket is put on. second stage: lower part of the rocket splits. then the main part of the rocket enters the space and revolve around the earth.
Newton's first law of motion tells me that I will remain in constant uniform motion unless I am acted on by an external force.
First law of motion is Object at rest/motion will stay in rest/motion unless an outside force acts upon it. The rocket ship isn't moving. But when you start it up, the gas molocules push downward at it is putting equal amout of force causeing it to move upward!
All objects, whether moving or not.
The cannon ball is not in motion until the fire and gunpowder pushes it upward and out of the cannon.
Vanguard I failed to launch. The rocket exploded on the launching pad. NACA ( yes, it was NACA at the time ) was in a hurry to catch up with the Soviets and the launch was pre-mature.
The US's first solid fuel rocket capable launching a satellite into orbit was named Scout. I think this was the first solid fuel rocket to carry payloads into orbit because the Soviet Union did not begin it's solid rocket program until later. It is possible the Minuteman ICBM may have been the first solid rocket to reach space but in a ballistic flight (go up and fall back down like a cannon ball), but I haven't been able to find the date of the first Minuteman sub orbital flight and both rockets were developed at about the same time.
the first rocket was
To place a satellite at a height of 300 km, the launching velocity should atleast be about 8.5 km s-1 or 30600 kmph. If this high velocity is given to the rocket at the surface of the Earth, the rocket will be burnt due to air friction. Moreover, such high velocities cannot be developed by single rocket. Hence, multistage rockets are used. To be placed in an orbit, a satellite must be raised to the desired height and given the correct speed and direction by the launching rocket At lift off, the rocket, with a manned or unmanned satellite on top, is held down by clamps on the launching pad. Now the exhaust gases built−up an upward thrust which exceeds the rocket's weight. The clamps are then removed by remote control and the rocket accelerates upwards. To penetrate the dense lower part of the atmosphere, initially the rocket rises vertically and then tilted by a guidance system. The first stage rocket, which may burn for about 2 minutes producing a speed of 3 km s-1, lifts the vehicle to a height of about 60 km and then separates and falls back to the Earth. The vehicle now goes to its orbital height, say 160 km, where it moves horizontally for a moment. Then the second stage of the rocket fires and increases the speed that is necessary for a circular orbit. By firing small rockets with remote control system, the satellite is separated from the second stage and made to revolve in its orbit.
