Rest and motion

In this Class 9 Science topic from “Describing Motion Around Us,” students learn how to identify whether an object is at rest or in motion by comparing its position with a reference point over time. They explore why rest and motion are relative, examine familiar examples such as moving vehicles, walking people, and stationary objects, and build a foundation for describing motion scientifically. The topic also prepares students to understand related ideas such as distance, displacement, and changes in position.
