Define gravitational force.
Answers
Answer:
Gravitational force is a force which acts on every object which has a mass. It is the very force which is keeping you on the ground. Gravity was discovered by Sir Isaac Newton. This S.I unit of force which includes gravity is N (newton - named after Sir Isaac Newton).
The gravitational force also known as gravity is a phenomenon of nature.
1. Gravitational force is the universal force of the earth by which all the elements of the earth are attracted to each other.
2. We can define Gravity as "The gravitational force is a force that attracts any two objects with mass."
3. It is called the "force of attraction" because it pulls all the elements together.
4. Gravity was invented by the renowned scientist Isaac Newton. His theory of Universal Gravitation says that "a universal force of attraction exists between all matter". The Newton law of gravitation considers gravity to be a force that causes a strong attraction between any two masses, with their magnitude being proportional to their product of the masses and inversely proportional to the square of the distance between them.
5. The theory of relativity coined by Sir Albert Einstein did not consider gravity as a force. It said "gravity as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass."
6. Gravity is considered to be the weakest force.
