How big does a clump of rock or how big does the mass of an object have to be before gravity makes it round like a planet?
The size of a mass does not determine the significance of gravity. Gravity is a fundamental force that exists between any two objects with mass, regardless of their size. However, the strength of gravity does depend on the masses of the objects and the distance between them.
No, there is no minimum mass required for gravity to exist. All objects with mass, no matter how small, have a gravitational pull on other objects.
No, gravity is a force that is created by the presence of mass. Without mass, there is no gravity.
Yes, the larger the mass of an object, the stronger its gravitational pull will be. However, the distance between objects also plays a significant role in the strength of gravity.
According to Einstein's theory of general relativity, there is no upper limit for the strength of gravity. However, in extreme cases such as black holes, the strength of gravity can become infinitely strong.
