2000) Gravity is a very essential part of life on earth. We are in the exact position in the sun's gravitational field to keep us in orbit and keep life ongoing on our planet. Gravity is a downward f ... Gravity is a downward force on any body of mass, the larger the mass of the body, the stronger the gravitational force. On earth the force is 9.8 N/Kg (Newton's per Kilogram) roughly, depending on wh ...
