The alka-seltzer rocket experiment demonstrates Newton's third law. The film canister rocket has a buildup of gas that wants to come out of the weakest spot making all the gas come out at once through the hole at the bottom. The gas comes out from the underside and pushes the rocket up. After it gets pushed up, air resistance slows it down and ...
The balloon rocket can be used easily to demonstrate simple physics, namely Newton’s third law of motion. [2] A common experiment with a balloon rocket consists in adding other objects such as a string or fishing line, a drinking straw and adhesive tape to the balloon itself. The string is threaded through the straw and is attached at both ...
Rocket engines operate by expelling propellant, which acts as a reaction mass and which produces thrust per Newton's third law of motion.All designs for electromagnetic propulsion operate on the principle of reaction mass.
In special relativity, the rule that Wilczek called "Newton's Zeroth Law" breaks down: the mass of a composite object is not merely the sum of the masses of the individual pieces. [82]: 33 Newton's first law, inertial motion, remains true. A form of Newton's second law, that force is the rate of change of momentum, also holds, as does the ...
A water rocket is a type of model rocket using water as its reaction mass. The water is forced out by a pressurized gas, typically compressed air. Like all rocket engines, it operates on the principle of Newton's third law of motion. Water rocket hobbyists typically use one or more plastic soft drink bottles as the rocket's pressure vessel. A ...
A reaction engine is an engine or motor that produces thrust by expelling reaction mass (reaction propulsion), [1] in accordance with Newton's third law of motion.This law of motion is commonly paraphrased as: "For every action force there is an equal, but opposite, reaction force."

A reactionless drive is a hypothetical device producing motion without the exhaust of a propellant.A propellantless drive is not necessarily reactionless when it constitutes an open system interacting with external fields; but a reactionless drive is a particular case of a propellantless drive that is a closed system, presumably in contradiction with the law of conservation of momentum.
