2. Galileo
3. Kepler
4. Copernicus

Answer 1

Correct Answer - Option 1 : Newton

The correct answer is Newton.

 

• Universal Law of gravitation was formulated by Sir Issac Newton. 

•  It states that Every body in universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between them.
  • The force acts along the line joining the two bodies.
  • The gravitational force is a central force that is It acts along the line joining the centers of two bodies.
  • It is a conservative force. This means that the work done by the gravitational force in displacing a body from one point to another is only dependent on the initial and final positions of the body and is independent of the path followed.
