sedateness is a force of attraction that exists between both two masses, each two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is the attraction that exists between altogether objects. (NASA gravity 2000) Gravity is a very inhering part of life on human race. We are in the rent position in the fair weathers gravitative field to keep us in orbit and keep life ongoing on our planet. Gravity is a downward force on any body of mass, the larger the mass of the body, the stronger the gravitative force. On earth the force is 9.8 N/Kg ( normalitys per Kilogram) roughly, depending on where you are on earth.
The original idea of gravity was discovered by Sir Isaac Newton (Jacob 1999). It is said that Newton was sitting under
an orchard apple tree tree and an apple fell from the tree striking him on the head. (What probably happened was that he watched an apple fall from a tree.) He concluded that on that point must be a force pulling all objects towards the ground, such as the apple and himself, and because the apple started at rest, there must be acceleration due to that force. Later with his cunning of the telescope, he discovered that larger bodies have a stronger gravitational pull.
It had been previously proven that the earth and other planets orbited around the sun. Because the sun was the largest body in the solar system, Newton concluded that larger bodies had larger and stronger gravitational fields.
As seen above, gravity is a force affecting 2 bodies. This is not totally exact because it does not broker in air resistance and friction. Even though gravitational acceleration is constant, air resistance affects free fall. For instance, if you took a turn over diver and a...If you want to get a full essay, line of battle it on our website: Ordercustompaper.com
