According to the universal law of gravitation, Every object attracts each other but if two human bodies are standing in opposite directions
Why does they not attract each other?
Answers
Answer:
The gravity that humans produce on earth cannot attract someone due to 4 things.
1. Earth’s gravity
Earth’s gravity influence is much stronger on humans than 2 humans on exert on each other , thus our gravity is too weak to overcome earth’s gravity and pull humans towards each other.
2. Friction
Friction is another reason why humans are not attracted to each other by gravity , The friction of 2 Humans standing nearby are resisting this force but it does little to no job , again because of gravity weakness.
3. Air
Air is matter , so it acts as a barrier that stops humans from being attracted to each other by the weak gravity , But again , little to no job.
4. Too little mass
The key to gaining more gravity is obtaining more mass , and comparing a human’s average mass to Earth’s , The Earth has a undeniably HUGE mass relative to the human , Thus the earth has a strong gravity , While humans don’t.
But if 2 humans were placed in an empty space with no gravitational force effecting them whatsoever , They will be attracted to each other but that will take millions of years (even billions) depending on the distance.
Every object that has mass exerts an attractive gravitational pull proportional to that mass. The seat, the walls around you, the ceiling, the TV, etc. The reason you don't feel it is because gravity is by far the weakest of the fundamental forces. The most massive object near any of us is the planet Earth. The gravitational pull from the planet completely overwhelms every other gravitational pull, fading them into insignificance, yet, if you pick something off the floor you are defeating the gravitational pull of the entire planet. That should tell you why you can't feel the gravitational pull from the person sitting beside you.
If you are talking of two people with mass 100 kg and seated 10 cm apart (that’s two obese people sitting very close indeed!), the force is about 6.7 x 10^-5 Newtons. Now, a Newton is itself a small force: it is the force exerted by a 100 g object (say a pack of butter) on your hand. 10^-5 Newtons would correspond to the force exerted by a milligram! Pick up one of the 1 mg masses that you can see in a chemical balance set of weights to see how much is the force!
