Answer :
Newton's law of gravitation says that the magnitude f of the force exerted by is f = Gmm/r² and acceleration due to gravity Gm/r².
What is force?
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
The gravitational constant, denoted by the capital letter G, is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's theory of general relativity.
f = Gmm/r²
Newton's law of gravitation says that the magnitude f of the force exerted by is f = Gmm/r² and acceleration due to gravity Gm/r².
