MCQ
When a satellite moves around the earth in a certain orbit, the quantity which remains constant is .........
- AAngular velocity
- BKinetic energy
- ✓Areal velocity
- DPotential energy
✓
Answer
Correct option: C.
Areal velocity
c
(c)
(c)
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.
