Laws of Motion: Force may be defined as a push or pull by one body to another. Balanced force are forces where the effect of one force is cancelled out by another. Unbalanced force are forces that are not equal in magnitude and may or may not act in the same direction. Inertia is the tendency of an object to maintain its initial state of motion. Newton related the concept of inertia to mass. Mass is a measure of inertia. 3 Laws of Motion: 1.) First Law (Inertia) - An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force. 2.) Second Law (Acceleration) - that the acceleration of an object is directly proportional to the net external force acting on the object and inversely proportional to the mass of the object. 3.) Third Law (Action and Reaction) - for every action (force) in nature there is an equal and opposite reaction.
Understand the Problem
The text provides a summary of the concepts related to the laws of motion, including definitions of force, balanced and unbalanced forces, inertia, and a brief overview of Newton's three laws of motion.
Answer
Newton's Laws of Motion: 1) Law of Inertia, 2) Law of Acceleration, 3) Action and Reaction.
The 3 laws of motion are: 1) The First Law (Law of Inertia) - an object at rest stays at rest, or in uniform motion unless acted upon by an external force. 2) The Second Law (Law of Acceleration) - force is the product of mass and acceleration (F=ma). 3) The Third Law (Action & Reaction) - every action has an equal and opposite reaction.

More Information
Isaac Newton formulated the three fundamental laws of motion, which describe the relationship between a body and the forces acting upon it, as well as the body's motion in response to those forces.
Tips
A common mistake is confusing the Second Law with just 'force equals mass times acceleration'; it's about the proportionality of force and acceleration.
