Here's a breakdown of what it means:
* Objects at rest stay at rest: If an object is not moving, it will remain stationary unless a force acts upon it. Think of a book sitting on a table. It won't move unless you push or pull it.
* Objects in motion stay in motion: If an object is moving, it will continue moving at a constant speed in a straight line unless a force acts upon it. Imagine a ball rolling across a smooth floor. It will keep rolling at the same speed in the same direction unless something stops it (like friction or a wall).
Key points to remember:
* Inertia: The tendency of an object to resist changes in its motion is called inertia. The more massive an object is, the more inertia it has.
* Force: A force is a push or pull that can change an object's motion.
* Straight line: The law applies to motion in a straight line, not curved paths.
