There is no need for air resistance, nor does the thrust need to push against anything. The energy of firing a rocket pushes the exhaust gasses out and, in accordance with Newton's Third Law, the gasses push back on the rocket with the same amount of force, but in the opposite direction. By firing gas jets or rockets that are not aligned with the center of mass, that force exerts torque, which allows a rocket to turn.

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
What causes a rocket to accelerate?
THRUST
What force does a rocket exert?
thrust
What makes a rocket move forward?
Thrust from the combustion of rocket fuel.
Which forces slow things down out of upthrust friction weight and air resistance?
Air resistance and friction. Weight can sometimes slow you down if your going up in like a plane or rocket. UpTHRUST THRUST=Push

During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?
thrust of the rocket engine
As the rocket is moving through the Earths atmosphere another force acts against the thrust from the shuttles engines. What is this force called?
Reaction force that is equal and opposite to thrust force from the rocket's engine.
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.
A rocket becomes progressively easier to accelerate as it travels upward from the ground mainly because?
The rocket's acceleration is created by the net force acting on it. There are three forces acting on the rocket: the thrust provided by the engines, gravity or weight, and air resistance. The acceleration is inversely proportional to the rocket's mass. This is Newton's Second Law: (acceleration) = (net force) / (mass) We need to think about the direction of the forces. The thrust acts upward (call this positive), and both gravity and air resistance acts downward (call these negative). So we get (acceleration) = (thrust - weight - air resistance) / mass A typical rocket engine will provide constant thrust as long as the fuel lasts. But as the engine consumes fuel, expelling the exhaust products out the back of the rocket, the rocket's mass decreases. This tends to increase the rocket's acceleration since acceleration is inversely proportional to the mass. In addition to the decreasing mass, the rocket's weight decreases as it moves farther from the center of the Earth--- this effect is described by Newton's Law of Gravity. The rocket's decreasing weight tends to increase its upward acceleration. The action of air resistance is more complicated, and ordinarily we ignore air resistance in simple models just to avoid the complication air resistance gives to the problem. In the standard air resistance model, air resistance scales with the square of the rocket's speed and the air density. The rocket is moving faster and faster, but the air density is also decreasing as it rises through the atmosphere. I think we can safely say the air resistance force decreases as the rocket gains altitude, but a detailed answer illustrating precisely how this force changes would require a numerical simulation. Hope this helps!
How many forces does a rocket have at lift off?
-- Gravity. -- Thrust of the rocket engines. Slightly after lift-off, as the vehicle begins to pick up some vertical speed, air resistance also appears.
Is thrust a verb?
It can be as in "He thrust his sword into his enemy", however it can also be a noun as in "The thrust of the rocket was enormous".
Does the thrust of a rocket need to be created by an explosion?
no, the thrust of a rocket relies on the trajectory of the rockets tilt and overall slanted angle. The rocket is sent via a useful queef, that blasts the rocket from the platform
What is the force that accelerates a rocket?
Thrust.
What causes a rocket to accelerate?
THRUST
What force does a rocket exert?
thrust
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.
