Detailed explanation-1: -Like most engines, rockets burn fuel. Most rocket engines turn the fuel into hot gas. The engine pushes the gas out its back. The gas makes the rocket move forward.
Detailed explanation-2: -We know that by newton’s third law of motion, Every action has an equal and opposite reaction. So as the fuel burns it escapes from the nozzle towards the earth. So the gases exert an equal and opposite force on the rocket. So this propels the rocket vertically upward.
Detailed explanation-3: -The propulsion of all rockets, jet engines, deflating balloons, and even squids and octopuses is explained by the same physical principle: Newton’s third law of motion. Matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains. Another common example is the recoil of a gun.
