Understanding Newton's First Law of Motion

Newton's First Law of Motion, also known as the Law of Inertia, states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. In simpler terms, this means that if something is not moving, it will not start moving until a force is applied to it. Similarly, if something is moving, it will not stop or change direction until a force causes it to do so.

Relevance in Daily Life:

• A book lying on a table will remain there until someone picks it up (an external force).
• A car will continue to move in a straight line at a constant speed unless the driver applies the brakes or turns the steering wheel (external forces).
