Which of the following statements are true about gravitational force? Identify all that apply. The gravitational force only acts between very, very massive objects. The gravitational force between an object and the earth is inversely related to the distance between the object's and the earth's center. The gravitational force can ALWAYS be accurately calculated by multiplying the object mass by the acceleration of gravity (m•g). The gravitational force acting upon an object is the same as the weight of the object. The gravitational force between two objects is independent of the mass of the smaller of the two objects. If object A gravitationally attracts object B with a force of X Newtons, then object B will also gravitationally attract object A with the same force of X Newtons. The doubling of the separation distance (measured from the center) between two objects will halve the gravitational force between the objects. It an object is placed two earth-radii above the surface of the earth, then the force of gravitational attraction between the object and the earth will be one-fourth the magnitude as on earth's surface. Orbiting astronauts do not experience a force of gravity; this explains why they feel weightless.
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.
