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 what this means:
* Object at rest: If an object is stationary, it will remain stationary unless a force pushes or pulls it.
* Object in motion: If an object is moving, it will continue moving at the same speed and in the same direction unless a force changes its speed or direction.
Examples:
* A ball sitting on a table will stay there until someone kicks it.
* A car traveling at a constant speed on a straight road will continue at that speed and direction unless the driver applies the brakes or steers.
Important Notes:
* No force means *no net force*. This means all forces acting on the object cancel each other out. For example, gravity acts on an object, but if the object is resting on a surface, the surface exerts an equal and opposite force, resulting in no net force.
* Friction can still act on an object, even if there is no external force. However, friction is a force, so it will eventually cause an object in motion to slow down and stop.
In essence, when no force acts on an object, it maintains its state of motion – whether that's at rest or in motion.
