Answer 1

Hey champ!!

——Here is your answer——-

In space rockets, gas is produced by burning propellants which are produced by burning of liquid,solid or a combination of the two.It uses all the newton’s laws of motion in it’s flight.When it is at rest in it’s launch pad, balanced force acts on it.It takes unbalanced forces to stop,change its direction or alter its speed.When the gas starts burning from the lower cavity the rocket experiences a thrust and unbalanced force acts on it which helps the rocket in flight.The thrust of the rocket continues due to the burning of the fuel or propellant.
