Both. The rocket is forced in one direction and the hot gasses are forced in the opposite direction.

When a rocket rises what is the reaction force?
A rocket in space operates off the expelled mass, from the conservation of momentum, dmv/dt = mdV/dt + Vdm/dt =0, The rocket is acceleration is mdV/dt = -Vdm/dt. The exhaust is Vdm/dt which is the force pushing the rocket forward as the exhaust goes out.
How does a rocket change its speed in space?
A rocket changes its speed in space by expelling high-speed exhaust gases through its engines. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. The rocket's engines push the exhaust gases backward, generating thrust and propelling the rocket forward, thus changing its speed.
What force from expansion of gases pushes rockets forward?
Thermal expansion of the combusting gases in the rocket nozzles (bottom of the rocket) pushes them against the outside air, and the equal-and-opposite reaction is to push the rocket upward.
Why does a rocket move?
By gases moving inside the rocket and then it will move forword.
How do rockets move?
a rocket moves when gasses expell from the back causing the rocket to move in the opposite direction a rocket moves when gasses expell from the back causing the rocket to move in the opposite direction
How the propulsion of jets and rockets is an application of newton third law motion?
For every action (force) there is and equal and opposite reaction (force). When fuel is burned in a rocket or jet, the hot expanding gases leave the rear of the engine. The opposite is the force pushing the rocket itself forward.
How do action-reaction explain how a rocket lift off?
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

When a rocket rises what is the reaction force?
A rocket in space operates off the expelled mass, from the conservation of momentum, dmv/dt = mdV/dt + Vdm/dt =0, The rocket is acceleration is mdV/dt = -Vdm/dt. The exhaust is Vdm/dt which is the force pushing the rocket forward as the exhaust goes out.
How does the first and third law of motion apply to a rocket launching?
1st. The rocket sets still until a force, burning fuel, causes a change in motion. 2nd. F=ma The force of the burning fuel causes an acceleration of the rocket. 3rd. Action/reaction. The action of hot burning gases leaving the rocket causes a reaction, which is the motion of the rocket in the opposite direction. Note: The exhaust does not need to hit the ground to cause the reaction. A rocket engine ignited in outer space will cause a change in the motion of the rocket.

What kind of newtons law of motion is illustrated if the force that accelerates a rocket into outer space is exerted on the rocket by the exhaust gases?
For every action, there is an equal and opposite reaction (Newton's third law of motion)..
A Diwali rocket is ejecting 20 gm of gases per second at a speed of 200mswhat is accelerating force on the rocket?
A Diwali rocketis ejecting 0.05 Kg of gases per second at a speed of 400m/s. What is the accelerating force on the rocket.
What force produced by expansions of gases that push a rocket forward?
thrust
What is the force produced by expansions of gases that pushes a rocket forward?
thrust
How does a rocket lift off the ground and what keeps a satellite in orbit?
A rocket can rise into the air because the gases it expels with a downward action force exert an equal but opposite reaction force on the rocket. Satellites in orbit around Earth continuously fall toward Earth, but because Earth is curved they travel around it.
