first law of motion because it defines the term force
action
the law of inertia
Newton's third law of motion is known as "action-reaction" law. This law states that for every action, there is an equal and opposite reaction.
The law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This law is known as Newton's First Law of Motion.
I have never seen it called that before. Perhaps whoever used this name meant that it is a law that applies in our real world - as opposed to any other law which you might make up, but which doesn't apply in our world.
The law of inertia (it relates to an object's resistance to the change in motion)
Newton's first law of motion is also known as law of inertia.
I know of no fourth law. The laws of motion are three.
Newtons first Law
The first law of motion is also known as Newton's law of inertia. It states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an external force.
newton's first law of motion is also known as LAW OF INERTIA. inertia is the property of a body by which every body if is in rest it tends to remain in rest and if in motion it tends to remain in motion.
An object in motion will stay in motion, at a constant velocity. This assumes that no net force acts on the object. This is known as Newton's First Law.
