Newton, Motion and Force
It is easy to recognize an object in motion and an object at rest. Super-sonic jets, race cars and even my mini-van can be objects in motion or at rest. What keeps an object at rest or in motion? What causes an object at rest to move? Furthermore, what causes an object in motion to stop? Well, the short answer to these questions is force, which is any influence that causes an object to change its shape or motion.
What is Newton's First Law of Motion?
Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by what we call an unbalanced force. Let's break this law down by defining some key terms. Velocity is the speed of an object in a specified direction. An unbalanced force is an external force that changes the motion of an object. When an object is at rest or moving at a constant velocity, all the forces acting on it are balanced.
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.
