Question

A point object is one whose size is ________ as compared to the distance it moves.

Answer 1

1. If the size of an object is very small compared to its covered distance, then it can be treated as a point object.
2. For Example, Earth can be treated as a point object for studying its motion around the sun.
3. This is because with respect to Sun the size of Earth is very small.
4. The sun is $109times$ wider than Earth, and it accounts for more than $99.8percent$ of the solar system's total mass.

Hence, a point object is one whose size is small as compared to the distance it moves.
