Then they don't go into space
if theres no gravity then anyone could fly, so
yes it is true
Jet planes fly with the help of Thrust and Lift produced by the jet engines.
Thrust and Lift. Gravity and drag make planes more difficult to fly.
Gravity and aerodynamic resistance.
No. Planes fly horizontally, but the concept of horizontal depends on the direction of gravity. Gravity pulls towards the center of the Earth, so "down" at the poles is the same as "down" at the equator, i.e. towards the center of the Earth.
Planes are able to fly against gravity by conquering it with another force. This force happens to be the lift created by the wings of the aircraft wihch allow it to fly.
Of course, planes can fly.
Because their wings/rotors are able to create an upward force bigger or equal to the pull of gravity.
No.
A combination of the thrust of the engines and the lift of the wings overcoming the drag of air resistance and the pull of gravity.
it only works up to about 10,00ft, that's how planes fly - you need to be careful to not go off to space if u get in a plane
