667 times 10 to the negative 11th meters cubed per kilogram seconds squared. Sir Isaac Newtons inspiration for the Law of Universal Gravitation was from the dropping of an apple from a tree. Determine the force of gravitational attraction between the earth 598 x 10 24 kg and a 70 kg boy who is standing at sea level a distance of 638 x 10 6 m from earths center.
The formula of Newtons law of universal gravitation is defined as.
Newtons insight on the inverse-square property of gravitational force was from intuition about the motion of the earth and the moon. In accordance with this law two point masses attract each other with a force that is directly proportional to the masses of these bodies m1 and m2 and inversely proportional to the square of the distance between them. M 2 is the mass of the second object. Newtons insight on the inverse-square property of gravitational force was from intuition about the motion of the earth and the moon.
