Answer:
Inverse relationship between orbital radius and orbital speed
Explanation:
Orbital speed is defined as the average speed or the instantaneous speed at a specific point in its orbit. The mathematical expression for the orbital speed is given by :
[tex]v_o=\sqrt{\dfrac{GM}{r}}[/tex]......(1)
Where
G is the universal gravitational constant
M is the greater mass body and a smaller mass body orbits around it.
r is the orbital radius.
So, form equation (1) the average orbital speed is inversely proportional to the average orbital speed. On increasing orbital radius, average orbital speed decreases.
