There is an attractive gravitational force between these objects. Considering that the force is universal, it apply sin any location at any time for every object with mass. The magnitude of the force is given by: Fgravitation = G M1M2 r2 the distance r is measured from the center of m1 to the center of m2. G is called the universal 0 gravitational constant whích has a value of G = 6.67 x 1011 The equation for the force shows that the gravitational force is shorter or weaker depending on the masses of two objects and the distance between them. Exercises; Determine the gravitational attraction between the earth and the moon? Suppose two persons with the same mass of 60 kg was separated 5m apart. What is the value of its gravitational attraction?
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.
