Question

Alet plane flies in the air because:
The gravity does not act on bodies moving with
high speeds
The thrust of the jet compensates for the force of
gravity
The flow of air around the wings causes an
upward force, which compensates for the force
of gravity
The weight of air whose volume is equal to the
volume of the plane is more than the weight of
the plane​

Answer 1

Answer:

Initially , when the plane is taking off, thrust force is more than the force of gravity. When it is in the air, the force of gravity is compensated by the thrustof the jet.

And when the plane lands, at that point of time , the thrust force is less than the force of gravity.
