Newton's law of gravitation has been ve...

Newton's law of gravitation has been verified experimentally. But there is enough indirect evidence of its truth. For example, gravitational force of attraction of earth is responsible for binding all terrestrial object on earth. The same force is responsible for holding the atmosphere around earth, for rainfall and snowfall on earth. the gravitational force alone is responsible for holding our solar system in place, and so on.
Read the above passage and answer the following questions:
(i) name any two prediction made on the basis of this law.
(ii) what values do you learn from this law ?

Text Solution

Verified by Experts

(i)The prediction about solar and junar eclips made on the bassis of this law- always come out to be true.
(ii) From universal law of gravitational, we learn the universal law of love not only for the entire humanity. But also for plants, birds, animals and other living beings. the entire universe is a globle village, wherein every creature deserves our love, affection and care.
