Question

Eli5: Why can’t two people pick each other up at the same time and essentially “fly”?

In: Physics

Answer 1

For every action there is an equal and opposite reaction.

So, when picking something up, you are able to pick something up because there is an opposite downwards force into the ground thanks to gravity. For two people to pick each other up at the same time, this opposite reaction does not exist and therefore it’s impossible in Earth’s gravity environment.
