Newton publicized his Theory of Universal Gravitation in the 1680s. It basically set forth the idea that gravity is a predictable force that acts on all matter in the universe, and is a function of both mass and distance. The theory states that each particle of matter attracts every other ...
Weight: The force by which an object is attracted towards earth is called weight. ltbr. Weight = mg=2xx10^-3xx10=0.02 [therefore F=ma]
