Give the applications of universal law gravitation .

Explanation

Newton's law of gravitation is applicable universally . So it is called as universal law of gravitation .
(i) Dimension of the heavenly bodies can be measured using gravitation law .
(ii) Eg. Mass of the Earth , radius of the Earth , acceleration due to gravity etc. can be calculated with a higher accuracy .
(iii) Helps in discovering new stars and planets .
(iv) ONe of the irregularities in the motion of stars is called " Wobble" lead to the disturbance in the motion of planet nearby.
(v) Here mass of the star can be calculated using law of gravitation .
(vi) Helps to explain germination of roots due to the property of geotropism .
(vii) Helps to predict the path of the astronomical bodies .
