Question

When a satellite moves around the earth in a certain orbit, the quantity which remains constant is (A) Angular velocity (B) Kinetic energy (C) Areal velocity (D) Potential energy

Tardigrade Admin · Accepted Answer

The path of a satellite moving around sun in a certain orbit is not exactly circular but elliptical with low value of eccentricity, e. Thus only areal velocity is constant.

Q. When a satellite moves around the earth in a certain orbit, the quantity which remains constant is

Angular velocity

Kinetic energy

Areal velocity

Potential energy

The path of a satellite moving around sun in a certain orbit is not exactly circular but elliptical with low value of eccentricity, $e$ . Thus only areal velocity is constant.
