The 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?
Every object in this universe, whether small or large exerts a force on every other object. What is the name of this force?
If the gravitational force is acting on each and every object in this universe then why is the space expanding?
Suppose a planet exists, whose mass and radius both are half of the earth. Calculate the acceleration due to gravity on the surface of this planet. The universal law of gravitation states that every object exerts a gravitational force of attraction on every other object. If this is true, then why don't we see the various objects in a room moving towards one another?
