A Description of Newton's First Law of Motion
Newton's First Law of Motion is often called the Law of Inertia because Newton's First Law is essentially just a restatement of inertia.
Newton's First Law of Motion states that if zero net (total) outside force acts on an object (or on a system of objects), the object will not accelerate. In other words, if zero net outside force acts on an object, it will do one of two things:

Is Net Force Zero?Now, let's see if you can determine when the net force acting on an object is equal to zero.
