Applications of Newton’s laws

In this Class 9 Science topic from “How Forces Affect Motion,” students learn how Newton’s laws connect forces with the motion of everyday objects. They apply the ideas of inertia, force, mass, acceleration, and action–reaction to explain situations such as pushing or pulling objects, walking, riding in a vehicle, using seat belts, and the recoil of a moving body. The topic also develops skills in identifying forces, drawing simple force diagrams, and using Newton’s second law to solve basic problems.
