The gravitational field is another name for the acceleration due to gravity, depending on position, abbreviated as a. The gravitational field near the Earth's surface has the special value g = 9.8 m/s2. You can assume that the radius of the Earth is REarth = 6,400 km. Calculate the gravitational field from this formula, at a height of 585 km above the surface of the Earth. Enter the result in m/s2. Round to one digit after the decimal point (i.e., the same number of digits as in g = 9.8 m/s2). Hint: You can use either kilometers or meters for the values of REarth and R in this formula, as long as you use the same units for both. These units cancel out.
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.
