 * New & Gravity**

Fnet = m • a This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.toc
 * Isaac Newton believed that gravitation forces were responsi for the acceleration of objects on the moon and on the earth.
 * Suppose we fire a cannon horizontally from a high moontain: the projectile will eventually fall to earth.
 * Newton reasoned that if the cannon projected the cannon ball with exactly the right velocity, the projectile would travel completely around the earth, always falling in the gravitational field last never reaching the earth;
 * Newtons Law of universal gravitation applies to all objects
 * Universal gravitation mass**
 * As the mass of either object or both object increases the force of gravitational atraction increases
 * Effects of mass on gravity**
 * Universal Gravitation Distance**
 * As the distance separating two objects increases the force of attraction is exponentially smaller.
 * Effect of distance on gravity**
