Thrust is independent of weight. In straight and level flight thrust operates forward, drag operates to the rear, weight operates downwards and lift operates upward. For a rocket, traveling straight up (away from the center of the earth), drag and weight operate downwards while thrust operates upwards.

The above answer appears correct (where "operates" is taken to mean "exerts force in the indicated direction") - additional discussion follows:
(I am assuming we are talking about a rocket or an aircraft for the purposes of this answer. I am also assuming that by weight, we mean mass)
The mass of a craft does not affect the thrust per se, that is, they are independent quantities as discussed below.
Since the thrust is a function of the type (efficiency) of engine and the amount of fuel delivered per second, a formula expressing the thrust will not include the mass of the craft directly, hence the independence.
However, of course, the thrust that a given craft can generate will be a function of the size of its engines, the type of fuel, and the amount of fuel delivered to the engine per unit time. Since the weight of the craft is partly determined by the size of the engine and the specific gravity of the fuel, there is a second order relationship between the weight of the craft and the thrust.
The acceleration of the craft under thrust will of course depend on the thrust and the mass according to Newton's Second Law, F=MA, or in this case, the form A=F/M.
PS: I'm not considering the relativistic realm either - you're on your own there!

What are the four forces that affect an airplane's ability to fly?
It is thrust, lift, drag and weightthat affect an aircraft's ability to fly. It is thrust that moves the aircraft forward through the air. The thrust overcomes drag and provides (with the wings) lift to overcome weight.
What is the difference between thrust and weight?
force applies perpendicularly is called thrust force which earths exerts on objests is weight
Which is the outward force created by an arch's weight?
Thrust
How does the lift thrust drag and gravity affect a helicopter?
Lift, thrust, drag, and gravity affects all flying objects and wildlife. The blades of the helicopter provide lift, drag and thrust.
Which must be overcome by a rockets thrust?
The payload's weight, and the weight of the rocket itself.
What are the four forces that affect an airplane's ability to fly?
It is thrust, lift, drag and weightthat affect an aircraft's ability to fly. It is thrust that moves the aircraft forward through the air. The thrust overcomes drag and provides (with the wings) lift to overcome weight.
How does weight affect how things fly through the air?
Weight affects the amount of lift required to raise the weight. Thrust determines how much power is required to move the weight and at what speed.
What are the four forces that act on an airplane in flight?
Lift, weight, thrust and drag.
What is the difference between thrust and weight?
force applies perpendicularly is called thrust force which earths exerts on objests is weight
How do propellers affect thrust?
that is a fine answer
What is the relationship of lift drag thrust and weight when the airplane is in straight-and-level flight?
Lift equals weight and thrust equals drag.
Four forces that effect a birds flight?
Weight and lift are two forces that affect a bird's flight. Two other forces are drag and thrust.
How an airplane flys?
lift and thrust overcome weight and drag
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.
Five factor that affect aerodynamic lift?
Shape as in the curvature of the wing (camber), Size as in the wing's size, Speed,Thrust , the weight of the aircraft, may be drag too.
Which is the outward force created by an arch's weight?
Thrust
What must overcome by a rocket's thrust?
The payload's weight
