Describe rocket propulsion.
 
The propulsion of rockets is based on the and
 
Newton’s third law states that “for everythere is an equal and oppositeand they always act on two different bodies.
 
When the net external force acting on a system isthe total linear momentum of the system is.
 
When fuel burns inside the rocket, hot gases are ejected atthrough the nozzle, producing a.
 
As the rocket’s mass continuouslyduring flight and no net external force acts on the system, its velocity progressivelyuntil it can even reach escape velocity.
 
To achieve very high speeds such as orbital or escape velocity, the rocket’s mass other than fuel must be asas possible.
