When can an object be considered as a point object ? Explain in brief.

Explanation

An object can be considered a point object if during motion in a given time it covers a distance much greater than its own size. For example, if a car of size ` 3` metres is moving a few hundred kilometre distance, then to study this motion, the car can be taken as a point object, since `3` m si very much less than few hundred kilometre distance.
