Choose the correct statement. In planetary motion

A

the speed along the orbit remains constant

B

the angular speed remains constant

C

the total angular momentum remains constant

D

the radius of the orbit remains constant

Text Solution

Verified by Experts

The correct Answer is:
c
The orbits of planets are elliptical. The speed of the planet and its angular speed (or angular frequency) keep changing. Since no net torque acts on the planet, its angular momentum remains constant.
