A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. Newton’s laws can be used to explain this his laws in the simplest terms can be explained like this: First law- Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force. Second law- Force is equal to mass times acceleration. Third law- ....
