Explanation:
* Inertia is the tendency of an object to resist changes in its state of motion. This means that an object at rest wants to stay at rest, and an object in motion wants to stay in motion at the same speed and in the same direction.
* Velocity is a vector quantity that describes both the speed and direction of an object's motion.
* When a force is applied to an object, it causes a change in its velocity. However, inertia resists this change.
Examples:
* A car at rest will remain at rest until a force, such as the driver pressing the accelerator, causes it to move.
* A ball rolling on a smooth surface will continue to roll at a constant velocity until a force, such as friction, slows it down.
* A person standing on a bus will move forward when the bus suddenly brakes because their body has inertia and wants to continue moving at the same velocity as the bus.
Newton's First Law of Motion (Law of Inertia):
This law states that an object at rest will stay at rest and an object in motion will stay in motion at a constant velocity unless acted upon by an unbalanced force. This law is a fundamental principle of physics and explains why inertia resists changes in velocity.
