How does gravity (weight) stop working when a plane is going up?


Gravity actually is still there: but a stronger force has taken over.


Imagine gravity as being a strong arm pulling the plane to the ground. It has limited strength (the weight of the aircraft). Now imagine another arm, lift, pushing up on the plane at the same time. If it's stronger than gravity, the plane will go up.

Gravity is still pulling down, but lift is stronger. And that's how an aircraft stays aloft!
