A satellite moving round the Earth constitutes
Correct answer: B. A non-inertial frame of reference
- A. An inertial frame of reference
- B. A non-inertial frame of reference
- C. Neither inertial nor non-inertial
- D. both inertial and non inertial
Explanation
A satellite orbiting the Earth is continuously accelerating toward the Earth (centripetal acceleration due to gravity). A frame undergoing acceleration is non-inertial, so the satellite constitutes a non-inertial frame of reference (option B).

About Satellite Motion and Orbital Velocity
Satellite motion uses gravitational force as the centripetal force required for circular orbit, giving relationships among orbital radius, period and orbital velocity. Questions cover geostationary conditions and weightlessness, while distinguishing orbital velocity, escape velocity and the satellite's tangential speed.
