wirte short note on gravitationnal
Answers
Answer:
Gravity, also called gravitation, is a force that exists among all material objects in the universe. For any two objects or particles having nonzero mass, the force of gravity tends to attract them toward each other. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.
Answer:
According to the law of gravitation,the earth attracts each object around it,towards its centre.The force with which the earth attracts a body is called the force due to graity on the body. It always acts vertically downwards at the centre of gravity of the body
Explanation:
Gravitational force is the force of attraction between any 2 bodies in the universe. It is independent of presence of 3rd body in between the 2 given bodies. It is a central force i.e. it acts along the line joining the centers of 2 bodies. It is independent of the medium between the 2 bodies. It is a long range force. It obeys inverse square law. It is negligible between 2 lighter bodies but become appreciable for massive bodies.
