well i was studying physics and learned that every objet that has mass has gravity and attract things like earth and moon. so why do we not do so.
answer quick and get 10pts.

well it causes acclerationand hence over a time there should be an effect

Hey! this is actually a good question...because it seems obvious at first that we should be drawn into each other if your Physics book is correct.
A couple of things are worth noticing - the gravitational force is very weak. Imagine if instead of "mass" being the source we were all large magnets. Everytime we got within a few inches of each other we would be stuck together!
The first measurements of the gravitational constant G were made around 1798 - long before digital instruments. It is amazing what these guys could figure out with stuff you can find in any hardware store.

The gravitational force pulling two objects together (assuming each object has a mass) is
F = M1 * M2 * G / R^2
where M1 and M2 are the masses, G is the gravitational constant, and R is the distance between the objects.
This law is valid for ANY two objects on a macroscopic scale, including two humans, a human and the Earth, or the Earth and the Moon, or the Milky Way and Andromeda galaxies.

Because the Earth's mass is so much bigger than us, it cancels out our masses attraction to each other.

We do attract each other, but that attraction is miniscule. Anything with matter has some gravitational pull but it usually is so unbelievably tiny that it never matters.

because there is not enough mass to do considerable amount of pulling to notice. we do, in a very small degree. it takes the whole worlds mass jus to kep us on the ground, and thats not even good enough cause we can jump off it.

I'm pretty sure that we do have some sort of nominal effect on each other, however it is too weak to feel.

We do attract each other , but the force is so small that it can't overcome the other forces present .

The earth's pull is so much greater than ours that we do not feel the minute pull of tiny objects.

I attract men.

YES WE DO!
Reread your PHYSICS book!
