Conclusion about gravitation
Answers
conclusion:
we conclude that The discovery of gravitation by Sir Isaac Newton, due to his observation of the falling apple, explained the movements of planets and satellites not only in our solar system but also in other systems as well. It explained why the Earth and other planets where spherical or nearly spherical in shape.If two electrons are separated by a small distance there is a gravitational force of attraction and an electrostatic force of repulsion between them. Since the gravitational force of attraction is much weaker the force of repulsion, the latter predominates. Thus, gravitational force is a weak force but exists over large distance
Gravitational force is the force that pulls a body thrown up in the air toward the earth. It is responsible for keeping all things on the earth in their proper position otherwise all things would be flying everywhere.
The gravitational force between two bodies at a distance apart is given by F=GMm/r*r where G is universal gravitational constant.
Gravitational force is a weak force but is very useful and has many wonderful and practical applications.
