Why is it that the Earth’s gravity is powerful enough to pull aeroplanes down from the sky if they didn’t move fast enough yet we can easily raise our arms in the air without feeling any force pulling on them?
In: Physics
I’m no expert and someone else will have a better explanation, but gravity isn’t as strong as you think it is. So when heavy as plane has to fly it has to have the speed to use the wind to give it lift so it can fly. It’s not necessarily because earths gravity is so strong. I’m not sure if I’m explaining it right.
