In order to be able to answer this question effectively and efficiently we have to consider the Newton's law of Universal gravitation which is given by the mathematical representation below;
Gravitational force, F = G (m1 × m2) / r^2.
Where G = Gravitational constant, m1 and m2 and the masses of body one and two respectively and r = distance.
So, we can deduce that the mass(in form of kinetic energy) increase at large distance and this makes the speed to reduce.
Landscape is what we see around us, our surroundings and things such as mountains and beaches. landscapes are constantly changing and landscape geography focus on the understanding of what factors lead to change
