The spacecraft generated an upward push force higher than the gravitational pull to the earth's surface.
What is Apollo11?
On July 16, 1969, Apollo 11 lifted off from Cape Kennedy with Commander Neil Armstrong, Pilot of the Command Module Michael Collins, and Pilot of the Lunar Module Edwin "Buzz" Aldrin aboard. They were sent into an initial orbit of 114 by 116 miles around the Earth. On July 20, 1969, Armstrong took "...one modest step for a man, one giant leap for mankind," as he said in a televised visual and audio broadcast seen by an estimated 650 million people.
A rocket will take off and continue to accelerate so long as the force thrusting it upwards is stronger than the forces pulling and thrusting it downwards (gravity and drag).
We can better grasp how forces cause objects, like rockets, to move thanks to Newton's first law. Unless an imbalanced force acts upon a stationary object, it will stay stationary. A moving object will also keep moving in a straight line at a steady speed unless it is being affected by an unbalanced force.
When the upward thrust force of a rocket is higher than the downward weight force of gravity, the rocket will launch. A rocket accelerates upward due to this imbalanced force. As long as there is an upward force produced by the thrust of the rocket engine, a rocket will continue to accelerate.
An imbalanced force is required for an object to begin moving. The forces pulling an object in one way are greater than the forces pushing it in the opposing direction, according to this definition. The imbalanced force, also known as the resultant force, is the difference between the forces pushing in one direction and the opposite direction.
At the moment of liftoff, a rocket is subject to two forces:
By forcing gases downward in the opposite direction, thrust propels the rocket higher.
Weight is the gravitational force that pulls the rocket down and toward the centre of the Earth. 9.8 newtons (N) of weight are present for every kilogramme of mass.
