INERTIA AND NEWTON'S FIRST LAW OF MOTION

This fundamental law describes how objects behave when forces are applied, laying the foundation for understanding motion and the natural world.

3. Understanding the Law of Inertia

4. Newton's First Law of Motion An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force. Formula: F = 0 → a = 0

5. Law of Inertia The tendency of an object to resist changes in its motion. Examples: A book on a table will remain still until a force is applied. A rolling ball will continue moving until friction or another force slows it down.

6. Key Points An object will maintain its state of motion unless a force is applied. Inertia is a property of mass. The more massive an object, the more inertia it has.

7. Real-World Applications Seatbelts in cars Airbags Helmets Spacecraft navigation

8. Inertia in Everyday Life A passenger in a moving car A bike ride A spinning top A satellite in orbit

9. Conclusion Newton's First Law of Motion is a fundamental concept in understanding the natural world.
