Laws of Motion — Class 9 Physics

This topic introduces the fundamental laws that govern how objects move and why they change their state of motion. It covers the three laws of motion given by Newton, along with the concepts of force, inertia, momentum a…

• Newton's first law: a body continues in its state of rest or uniform motion in a straight line unless acted upon by an unbalanced external f…
• The first law is also called the **law of inertia**.
• **Inertia** is the natural tendency of a body to resist change in its state of rest or uniform motion.
