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.

When a rocket rises, the reaction force is the force pushing downwards on the rocket caused by the expulsion of exhaust gases in the opposite direction. This reaction force propels the rocket upward according to Newton's third law of motion.

Q: When a rocket rises, what is the Reaction Force?

A: Pressure pushing the exhaust gases DOWN, out of the rocket. (Key word, DOWN.)

The reaction force would be the thrust: force that propells the object forward.

thrust is action (force), acceleration of rocket mass is result of equal and opposite reaction

Rockets have an exhaust of hot gas, moving rapidly away from the rocket, which is the action, and the reaction is that the rocket is propelled forward.

When a rocket rises what causes the action forces?

When a rocket rises, the action forces are generated by the rocket's engines producing thrust. This thrust pushes against the ground, creating an equal and opposite reaction force that propels the rocket upward.


What is Rockets reaction force?

Rocket reaction force, also known as thrust, is the force exerted by a rocket engine to propel the rocket forward. This force is generated by the combustion of fuel in the rocket engine and is directed opposite to the direction in which the rocket travels. The magnitude of the thrust determines the acceleration of the rocket.


What type of force launches a rocket?

The force that launches a rocket is generated by the rocket engines thrusting against the ground, creating a reaction force that propels the rocket upward. This force is known as thrust force.


Acceleration of a rocket is which type of force contact or non contact?

Acceleration of a rocket is due to a non-contact force known as thrust. Thrust is generated by expelling mass from the rocket at high velocities, resulting in a reaction force that propels the rocket forward.


What action-reaction forces are involved when a rocket engine fires?

When a rocket engine fires, the exhaust gases are expelled downward, creating a thrust force that propels the rocket upward. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Therefore, the rocket experiences a reaction force pushing it in the opposite direction to the expelled gases.
