gravity you idiot. Become weightless, then talk.
Fundamentally same reason with the why you can't lift yourself when you breath out
Air .
If ppl cant lift there arms high in the air
Because planes need air pressure against their wings to generate lift.
Airplanes use air for lift and for thrust. If there's no atmosphere, they can't fly. Even a jet engine needs to burn and compress air.
it helps you get lift beneath your board, bike, or skates, giving you air to do tricks you cant do with all the wheels touching the ground,
No it can not fly on mars because theres no air for it to create lift. Helicoptors can only fly on earth and they cant fly at high altitudes.
Helicopters need air for the rotor to generate lift, and as the moon hasn't got an atmosphere a helicopter won't go anywhere.
Air Lift Group RAAF was created in 1987.
Hot air is less dense then the surrounding air, meaning it's lighter then regular air, allowing it to naturally lift. If something catches that lifting air, and the air is so light that it can lift the required weight up, then it will lift. That's why a hot air balloon requires hot air to lift.
The rules are very basic The ball cant touch your foot you cant use the curved side of the stick you cant lift the ball dangerously you need to be in the 'D' to score a goal you cant lift your stick dangerously and have fun!
