It's a combination of centrifugal force and gravity that allows constant acceleration of a rotating object? also is it just coincidence that the most dense objects are near the sun?

I am not sure what your asking in your first question. An object that is rotating will continue to rotate unless acted upon by an external force (Newton's first law of motion). In order to obtain "constant acceleration" you have to apply constant thrust. Also, enough centrifugal force can nullify the effects of gravity. For example, if Earth had a rotation of only 2 hours, 15 minutes per day (~18,000 mph), the centrifugal force would overcome Earth's gravity and break the planet apart.quincy harman said:It's a combination of centrifugal force and gravity that allows constant acceleration of a rotating object? also is it just coincidence that the most dense objects are near the sun?
Constant acceleration of gravity is the rate at which an object falls towards the ground due to the force of gravity. It is approximately 9.8 meters per second squared (m/s²) on Earth.
The equation for calculating constant acceleration of gravity is a = g = 9.8 m/s², where "a" represents acceleration and "g" represents the force of gravity. This equation is derived from Newton's second law of motion.
No, constant acceleration of gravity varies depending on the mass and distance of the object from the center of the planet. It also varies slightly at different locations on Earth due to factors such as altitude and latitude.
Constant acceleration of gravity is a fundamental concept in physics and is used to explain the motion of objects falling towards the ground. It also plays a crucial role in understanding the laws of motion and the behavior of objects in the universe.
Regardless of the mass of an object, all objects will accelerate towards the ground at the same rate due to the force of gravity. This means that a feather and a brick, when dropped from the same height, will reach the ground at the same time.
