Comment on Make gravity your bitch
Reddfugee42@lemmy.world 6 days agoIn a system where gravity is pulling on your hand, which is stronger, the force of the earth pulling in your hand, or the force of your hand pulling on the Earth?
Answer: it’s a trick question. In such a system, both sides feel the force equally

if we’re talking gravity physics, the earth, by basically every possible kilogram of mass imaginable to the human mind. But this goes without saying, because you stick to the earth, the earth doesn’t stick to you, so.
Of course technically, the force is applied to both objects, but considering the scale mismatch, one of these things is not like the other.

No you’re both drawn to the local center of gravity which is on a direct line between both bodies’ centers of mass and is proportionally closer to the object of higher mass.
That’s not really relevant in collided objects per se, but it means you and the earth both pull each other equally to a point that happens to be located ever so slightly away from the center of the earth. Well you would if there weren’t a ton of other gravitational influences including the non uniform shape and density of the earth that make you basically rounding error in terms of gravitational force. But you do impact it
