Suspend all disbelief and imagine digging to the center of the Earth, there you dig out a small spherical chamber, you sit in the middle, do you float or are you depatched violently to the wall around you instantaneously.
Would the same hold true for a black hole? (theoretically, of course.)Doc Al said:..the gravitational pull of the Earth's mass from one side exactly counters the pull from the Earth's mass from the other side--the net effect is that everything cancels out and there is zero gravitational field at the center...
Doc Al said:Think of each piece of the Earth's mass as exerting its own gravitational pull. On the surface, the resulting pull from all the Earth's mass is the usual force acting towards the center of the earth. But at the Earth's center itself, the gravitational pull of the Earth's mass from one side exactly counters the pull from the Earth's mass from the other side--the net effect is that everything cancels out and there is zero gravitational field at the center.
Yes. (Which is why I said you'd remain motionless relative to the Earth.)Jim1138 said:If you were in a chamber at the center of the Earth's mass, I would think that while you would "fall" toward the moon, the Earth would as well. Wouldn't the Earth's and your acceleration pretty much cancel out?
The center of gravity is the point within an object where the force of gravity is evenly distributed in all directions. It is also known as the center of mass.
The center of gravity is calculated by finding the weighted average of the mass distribution within an object. This can be done using mathematical formulas or through physical experiments.
The center of gravity is important because it determines the stability and balance of an object. If the center of gravity is too high or too low, the object may be more prone to tipping or falling over.
Yes, the center of gravity can be changed by altering the distribution of mass within an object. For example, adding or removing weight from one side of an object can shift its center of gravity.
The center of gravity affects motion by influencing the direction and stability of an object's movement. Objects with a lower center of gravity tend to be more stable and have smoother motions, while objects with a higher center of gravity may be more prone to tipping or swaying.
