universal law of gravitation States that every object exerts a gravitational force of attraction on every other object. if this is true, why don't we notice such forces? why don't the two objects in a room move towards each other due to this force?

The magnitude of the gravitational force acting on either of two 1 kg masses separated by 1 meter as a result of one another is just 6.67*10^-11 N.
Whereas, the frictional force acting on either mass (assuming them to be made of rubber and resting on concrete) is approximately 10 N.
So the force that restrains their movement (friction) is approximately 150 billion times stronger than the force that could move them (gravity)!
