The combustion of rocket fuel ejects a mass of material at high velocity. In accordance with Newton's third law, the momentum of the ejecta generates an equal and opposite reaction - which propels the rocket forward.
The propulsive force of a rocket engine is called thrust. It is the force that propels the rocket in the opposite direction to the exhaust expelled from the rocket engine.
A rocket accellerates in whatever direction it's pointed. Another way to put this is to say that a rocket accelerates in the opposite direction of its engine exhaust. See Newton's 2nd law of motion.
The force that accelerates an object is called net force, which is the total sum of all forces acting on the object. This force causes a change in the object's velocity, resulting in acceleration according to Newton's second law of motion (F=ma).
When a pitcher throws a baseball, the force from the pitcher's hand accelerates the ball, changing its velocity. When a car applies brakes, the force of friction between the tires and the road slows down the car, changing its velocity. When a rocket launches into space, the thrust from the engines accelerates the rocket, changing its velocity.
Momentum is the product of an object's mass and velocity, so a rocket with high momentum will have more force upon launch. Velocity is the speed at which the rocket is moving, which affects how quickly it accelerates and gains height. Both momentum and velocity are crucial for determining the rocket's trajectory and performance during launch.
Thrust.
As a rocket burns fuel, it expels exhaust gases. When the gases are forced out of the rocket, they exert an equal and opposite force on the rocket. A rocket can rise into the air because the gases it expels with a downward force exert an equal but opposite force on the rocket. As long as this upward pushing force, called thrust, is greater than the downward pull of gravity, there is a net force in the upward direction. As a result, the rocket accelerates upwards.-information from Prentice Hall, Science Explorer: Physical Science

That is called gravity.

For every action, there is an equal and opposite reaction (Newton's third law of motion)..
Presumably the most important force on an accelerating space shuttle is the force of the rocket engines (thrusters). Certainly other forces are present, including gravity and air friction.
The force that accelerates an object is called net force, which is the total sum of all forces acting on the object. This force causes a change in the object's velocity, resulting in acceleration according to Newton's second law of motion (F=ma).
