//**Definitions:**//

//**Axis**// - Straight line around which ration takes place. //**Centripetal Force**// completely around the Earth always feeling in the gravitational field but never reaching the Earth.
 * //Rotation -//** Object turns around an internal axis.
 * //Revolution -//** Object turns around an external axis.
 * //Linear Speed -//** Distance / Time.
 * //Trangential Speed -//** Speed along a circular path.
 * //Ratational//** //Speed -// Number of rations per unit of time.
 * //**Examples:**// Carousel horses travel at same ratational speed but different tangential speed.
 * Tangential speed is radial distance time the rotational speed: V = r w
 * Force that causes an object to follow a circular path.
 * Ex. Force holding occupants safety in a rotating carnival ride.
 * //Newtons and Gravity//**
 * Issac Newton believed that gravitation forces were responsible for the acceleration of objcets on the moon and an the earth.
 * Suppose we fire a cannon horizontally from a high mountain; the projectitle will eventually fall to earth.
 * Newtons reasoned that if the cannon projected the cannon ball with exactly the right velocity, the projectile would travel
 * //Universal Gravitational and Mass//**
 * As the mass of either object or both object increasing, the force of gravitaitional attraction increase.
 * As the distance separating two objects increasing, the force of attraction is exponential smaller.
