Kinetic Theory
The kinetic energies of a planet in an elliptical orbit about the Sun, at positions A, B and C are KA, KB and KC, respectively. AC is the major axis and SB is perpendicular to AC at the position of the Sun S as shown in the figure. Then
KA < KB < KC
KA > KB > KC
KB > KA > KC
KB < KA < KC
B.
KA > KB > KC
Speed of the planet will be maximum when its distance from the sun is minimum as mvr = constant
Point A is perihelion and C is aphelion.
Clearly, VA> VB>VC
So, KA>KB>KC
