![]() At the same time, the force of gravity follows certain rules and can be stated as a fact because it has a fixed relation with the masses between which it is acting and the distance of their separation, so gravity is also a law. Since gravity is a natural phenomenon that can be explained, it is a theory. It is a scalar quantity, and its value does not change with the place.Īns: A scientific theory explains why and how a thing occurs. Whereas gravitational constant is equal to the pull force between two point masses of 1 kilogram each separated by a distance of 1 meter. It is a vector quantity and its value changes from place to place. Differentiate between acceleration due to gravity and universal gravitational constant.Īns: Acceleration due to gravity is acquired by a body because of the gravitational pull of the earth. We have provided some frequently asked questions about gravity here: The gravity of the earth holds all the objects close to its surface including the atmosphere. This force of attraction depends on the mass of the interacting objects and the distance between their centres. ![]() The force that causes a rock to roll downhill.\(\Rightarrow F = G\frac\)īased on Newton’s law of gravitation, we can conclude that the force of gravitation is a mutual force that acts between all the objects in the universe.The force that causes a lock of your hair to fall to the floor after it has been cut off.The force that causes a jump rope to come back to the ground after you swing it over your head.The force that causes a balloon that is out of helium to come back down to the ground.The force that causes a piece of paper that is blowing in the wind to eventually come back down to Earth. ![]()
