Question

All planets, including Earth, revolve around the Sun. The Sun is

• A. at rest
• B. in motion
• C. at rest with respect to the Earth
• D. in motion with respect to the Earth

Answer 1

The correct option is D

in motion with respect to the Earth

A body can’t be in a state of absolute rest or motion. It is always defined with respect to an observer. If we consider the motion of the Sun with respect to itself, it is at rest. Any body is at rest with respect to itself as its position doesn’t change with time. However, the Sun changes its position continuously with respect to us. So, with respect to Earth, the Sun is in motion.
