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 universal law of gravitation states that every object exerts a gravitational force of attraction on every other object. It is true, but we don't notice such forces because here on the earth no object has an extremely large mass. Therefore, the gravitational forces between the two objects are so weak that they can't be noticed.
In a room, two objects don't move towards each other due to the gravitational force of attraction because this force is very weak as their masses are very small.
