An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Here's a breakdown:
* Inertia: This is the tendency of an object to resist changes in its motion. The more massive an object is, the more inertia it has.
* Rest: If an object is at rest, it will stay at rest unless something pushes or pulls on it.
* Motion: If an object is in motion, it will continue moving at the same speed and in the same direction unless something acts upon it.
* Unbalanced force: This is a force that is not countered by an equal and opposite force. Examples include friction, gravity, or a push or pull.
Examples:
* A book sitting on a table will stay there unless someone picks it up or something knocks it off.
* A ball rolling across a smooth floor will continue rolling in the same direction and at the same speed unless something stops it, like friction or a wall.
* A car moving at a constant speed will continue moving at that speed unless the driver steps on the brakes or the gas pedal.
In essence, the first law of motion tells us that objects will maintain their state of motion unless acted upon by an external force.
