Question

Why kinetic energyi is maximum at perigee in elliptical orbit of planet therotically

Answer 1

In simple words, velocity depends on area vector... The condition here is that there product remains constant at any point on the elliptical orbit.. At perigee area vector is minimum.. Thus velocity has to be maximum here.. And kinetic energy is proportional to the second degree of velocity.. Similarly the quantities will be minimum at apogee

Answer 2

Answer:

All planets travel in an ellipse around the sun, but the shape of that ellipse oscillates," he explains. "When the Earth's orbit is more elliptical, the planet spends more time farther away from the sun, and the Earth gets less sunlight over the course of the year
