Universal Law of Gravitation Worksheet Newton's Universal Law of Gravitation (first stated by Newton): any two masses m, and m, exert an attractive gravitational force on each other according to m, m, F = G This applies to all masses, not just big ones. G = universal constant of gravitation = 6.67 · 10-" N m² / kg² (G is very small, so it is very difficult to measure!!) Don't confuse G with g: "Big G" and "little g" are totally different things. Practice problems: 1. Consider a space shuttle which has a mass of about 1.0 x 10 kg and circles the Earth at an altitude of about 200.0 km. Calculate the force of gravity that the space shuttle experiences. (for the mass of the earth refer to the reference table page 1) 2. What is the gravitational force between two identical 50,000 kg asteroids whose centers of mass are separated by 1000 m?
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.
