A student said, "The Earth moves around the Sun". In this context, discuss whether an object kept on the Earth can be considered to be at rest.

Whether an object is at rest or in motion depends upon the reference point chosen for observation.

An object kept on the Earth appears to be at rest with respect to its surroundings on the Earth because its position does not change relative to nearby objects. For example, a book lying on a table remains at the same position with respect to the table and the room.

However, the Earth is continuously rotating about its axis and revolving around the Sun. Therefore, every object present on the Earth also moves along with it. Hence, with respect to the Sun or an external observer in space, the object is in motion.

Thus, an object kept on the Earth can be considered at rest with respect to the Earth, but not with respect to the Sun.
