What is the gravty of the earth

Gravity expresses the force that causes the attraction of two objects to each other, the same force that causes the fall of objects towards the Earth, the rotation of planets around the sun, and gravity is one of the four major forces in nature. It is worth mentioning that in 1680 the world Isaac Newton The law of the expression of gravity, and stated the existence of a proportional fit between the force of gravity and the mass of the two fingers attracted to each other, as well as an inverse relationship between them and between the square distance

The sun's gravity keeps the earth in orbit, helping to maintain an appropriate distance between them, thus enjoying the sun comfortably. Gravity maintains the presence of the atmosphere around the earth, which keeps us breathing and life. Gravity keeps connecting the world with each other.
