All these questions can be understood through the concept of gravitation. The Gravitational force is a universal force of attraction that acts between objects with mass and is one of the fundamental forces shaping the universe. In this section, we study the nature of the gravitational force for objects as small as ourselves and for systems as massive as entire galaxies. We show how the gravitational force affects objects on … Gravity is the law that every object with mass attracts every other object in the universe in proportion to each mass and inversely proportional to the square of the distance between them. The force of gravity , F is written using the gravitational constant, G, as [7] for two masses, m, and m′ separated by a distance r. Learn what gravitational force is, how it acts between any two masses, and how it affects our daily life. Find out the formula, properties, principle of superposition, and solved examples of gravitational force .
