How is gravity and thrust both involved when launching a rocket?

Gravity plays the major role in the launch.. a rocket has to cross the escape velocity so as to get out of the atmosphere. Escape Velocity is the speed at which any space shuttel or rocket or anything has to achieve if it wants to escape the earth's gravitational field. Gravity attracts the rocket and all the things coming from the space and going in to the space from the earth towards itself.. that is the reason that whenever you jump, you come back to earth!!!

∙ 11y agoWhile the rocket is standing on the ground, and during the launch, gravity is always
trying to keep the rocket on the ground, or return it to the ground. So it has to keep
firing its engines to stay up and continue rising higher.
But after a while, if it's traveling fast enough and in the right direction, then gravity
holds it in an orbit around the Earth.

If there were no gravity (and no air friction; no cross winds; and the earth stands still), all you need to do is to give the rocket a nudge and it will move away from you for eternity-- Newton's 1st Law of Motion. As a rocket being launched on earth, its engines have to generate enough thrust to overcome all the negative forces (gravity, air friction, cross winds, and earth's rotation) plus some more, then the rocket can lift off and go into an orbit -- Newton's 2nd Law of Motion.

∙ 12y agoThe gravity affects the rocket after it is a few metres up and in 3-7 seconds the firework rocket is pulled down by the gravity.
Wiki User
∙ 11y agodownwards, the firework rocket is pulled downwards that's why the rocket going at some distance slows down and stops......
Wiki User
∙ 10y agobeacuse without upthrudst the space rocket would stay stationary and could therefore not go to space.

What forces are involved when a rocket launches?
I know one of them is Thrust. One is gravity. Another is upthrust.
Why does a rocket need a large thrust on take off from the earth?
The rocket has to overcome the pull of gravity.
Center of gravity on a rocket?
It is the point on the rocket where it balances it self, with the pull of gravity, and the amount of thrust it applies back on the ground to move up.
How many forces acting are on a rocket?
There are four forces acting upon a rocket these are: Thrust, Gravity, Drag and Lift.
During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?
thrust of the rocket engine
What Are Forces Involved in Launching A rocket?
Thrust, gravity and upthrust help launch a rocket.

What is launching of rockets?
A rocket is said to launch when it leaves the ground -- is thrust into the sky.
What are forces acting on a rocket?
Thrust & gravity.
What are 2 forces acting on a rocket?
Thrust & gravity.
How do thrust drag and gravity affect a hydro-rocket?
Thrust - is the force pushing it forwards Drag - the force acting against the rocket Gravity - the force acting upon the rocket trying to push it towards the centre of the earth
Why does a rocket need a large thrust on take off from the earth?
The rocket has to overcome the pull of gravity.
Center of gravity on a rocket?
It is the point on the rocket where it balances it self, with the pull of gravity, and the amount of thrust it applies back on the ground to move up.
If a rocket's thrust equals weight of rocket will the rocket maintain a fixed height?
If and only if all of the thrust is in the opposite direction of the gravity vector ("straight down"). If any of the thrust has horizontal component, it will travel a distance but lose height.
How many forces acting are on a rocket?
There are four forces acting upon a rocket these are: Thrust, Gravity, Drag and Lift.
A rocket will move upward as long as the thrust is greater than the force of gravity?
Actually for some time even after the thrust is no longer greater than gravity. When the rocket's thrust is greater than gravity, it will be accelerating (its velocity upwards will increase). When the rocket's thrust is no longer greater than gravity, at that moment it will still have an upward velocity, so it will still travel upwards - it will only travel more and more slowly upwards as gravity starts to sap the rocket's upward velocity towards zero. Once its velocity reaches zero, if gravity is still winning over the rocket's thrust (if any), then it will start to fall back towards the ground.We are assuming a simplistic model (no air resistance, no super-unlucky collisions with meteors, etc.), but this is the basic idea.
What is required for a rocket to lift off into space?
thrust that is greater than earth's gravity
