Gravity, also called gravitation, is a force that exists among all material objects in the universe. For any two objects or particles having nonzero mass, the force of gravity tends to attract them toward each other. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies. It also operates over all distances, no matter how small or great.
Gravitation is one of the most studied phenomena in physics. Isaac Newton defined its behavior with his famous Law of Universal Gravitation. Newton hypothesized that the force of gravity between any two spherical objects of uniform density is directly proportional to the product of their masses, and inversely proportional to the square of the distance between their centers. According to this law, if m1 and m2 are the masses of two objects, and if their centers are separated by a distance d, then the gravitational force (f) between them is given is given by the following formula:
gravity is the force which attract the objects towards it.for ex.A fruit falling from the tree . it is due to gravitational force. therefore we cannot float in the air we cannot float in the air .this theory was given by sir isaac newton.
