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.
What is a device that is driven forward by a powerful stream of hot gas?
A Rocket
How does a rocket achieve lift?
A rocket achieves lift by pushing back the air column
What makes a rocket move forward?
Thrust from the combustion of rocket fuel.
How can a rocket change its velocity?
It could - but that's not the idea (except from start to whatever velocity you select). Since the rocket must reach either escape or orbital velocity (25000 mph or 18000 mph), if you could start off with that speed, the sudden jerk would tear it apart.
How do the principles of a water bottle rocket relate to real rockets?
Thy operate on the same principle. The water going backwards has momentum that is balanced by the rocket going forward.

A rocket lifts off by pushing down on the ground which then pushes the rocket up?
The propellant

How does a rocket moves forward?
Rockets are propelled forward by thrust generated by the combustion of rocket fuel and controlling the direction of the exhaust.
Action-reaction engines that propel an object forward?
a rocket

Why does a bottle filled with alcohol thrust forward when a match is lit in front of it?
For the same reason that a rocket goes into space. As you ignite the alcohol the products made will be gases that will be expelled from the bottle backward. Newton's third law of motion says that for every action there is an equal and opposite reaction. So pushing the gases backwards means that the gases push the bottle forwards.
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.
A rocket is pushed forward as a reaction to?
The rocket is pushed forwards by the reaction to the force ejecting gas in the opposite direction to the direction of travel of the rocket. Rocket flight is an example of Newton's 3rd law of motion, which states that every action (force) has an equal and opposite reaction. In this case, the action is the ejection of rocket gas and the reaction is the forward force on the rocket.
How water bottle rocket fly?
the rocket is pushing water downwards which means that the water pushes the rocket upwards very hard that it can overcome gravity and fly.
