Detailed explanation-1: -The relativistic point of view would be that the space around the Earth is compressing, but the atoms of the Earth resists this compression. This means that the surface of the Earth is constantly accelerating upwards.
Detailed explanation-2: -At different points on Earth’s surface, the free fall acceleration ranges from 9.764 to 9.834 m/s2 (32.03 to 32.26 ft/s2), depending on altitude, latitude, and longitude. A conventional standard value is defined exactly as 9.80665 m/s2 (32.1740 ft/s2).
Detailed explanation-3: -Acceleration is a change in velocity, either in its magnitude-i.e., speed-or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant.
Detailed explanation-4: -According to the theory of general relativity, why does the moon orbit the earth? the gravitational force between the two objects is stronger than the centrifugal force.
