Inertia
In this Class 9 Science topic from “How Forces Affect Motion,” students learn how inertia describes an object’s resistance to any change in its state of rest or motion. They explore Newton’s first law of motion, understand how mass affects inertia, and connect the idea with everyday examples such as passengers moving forward when a vehicle stops suddenly. The topic helps students distinguish between balanced conditions and the force needed to change motion.
