Some people dismiss the validity of scientific theories by saying they are “only” theories. The law of universal gravitation is a theory. Does this mean that the scientists still doubt its validity? Explain.
Whether the scientists doubt the validity of the law of universal gravitation.
Answer to Problem 20TE
The universal law of gravitation is a theory, but scientists do not doubt its validity.
Explanation of Solution
According to the law of universal gravitation, every mass gets attracted to every other mass when both come in contact with some force. This force is linearly dependent on the product of the attracting masses. While, as the square of the separated distance, the masses have an inverse effect on this force.
Even though the gravitational law is a theory, but it has enough evidence to support its validity. And it gives appropriate reasons behind the existence of gravitational force, which is universal. Unless another model or theory gets established, the scientist does not doubt its validity of the law of gravitation.
Conclusion:
Therefore, the universal law of gravitation is a theory, but scientists do not doubt its validity.
