Rockets can go in space but aeroplanes can only fly in air. Why?
Answers
Because Rockets have a propelling engine that propels the rocket to a perpendicular/ parabolic path through which the rockets goes out of earth orbit.
whereas the Airplanes have thrusting engines which thrust the airplane in an parallel/ antiparallel direction of air.
I hope this will clarify your doubts

● The inertial velocity of rocket is equle to the escape velocity .
[And, escape velocity means the minimum velocity / speed
needed by a object to escape from the gravitational force of
earth.]
● But the minimum velocity of a aeoplane is not equal to escape
velocity of the earth.
● Hence, the rocket can go into space but not the aeroplane, yet it
fly in air.
