A chair that for some reason won't move even after being pushed.
Explanation:
Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.
Newton's 1st law of Motion: An object in motion tends to stay in motion. An object at rest tends to stay at rest unless acted on by a net force. If acted on my a net force, an object will accelerate.
