Explanation:
No, the acceleration due to gravity is not constant. It can vary in different places. It depends on the distance from the centre and the gravitational force exerted by the planet on the object. On the surface of the earth, all object fall with an acceleration of somewhere between 9.78 and 9.82 m/s^2 depending on latitude, with a conventional standard value of exactly 9.80665 m/s^2.
What are these:-
(i) The Product Rule is that the derivative of a product of two functions is the first function times the derivative of the second function plus the second function times the derivative of the first function.
(ii) Newton's inverse square law states that gravitational attraction force between two point masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
(iii) The gravitational constant called 'G' is physics equation, is an empirical physical constant. It is used to show the force between two objects caused by gravity. The gravitational constant appears in Isaac Newton's universal law of gravitation. G is about 6.673 * 10^-11 Nm^2/kg^2.
(iv) Newton's law of universal gravitational states that every particles attracts every other particles in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of distance between them. Universal law of gravitation equation → F = G * M * m/r^2
