The Law of Inerita
Newton's first law the law of Inertia states " An object at rest remains at rest, and an object in motion remains in motion unless acted upon by an unbalanced force." An object not moving is considered at rest and will stay at rest unless acted upon by an unbalanced force. Objects in motion will stay in motion unless acted upon by an unbalanced force. An object at rest will not move unless acted upon by an unbalanced force, that unbalanced force is Friction. Friction causes an object to move or stop moving. An example is a ball at rest will begin moving and eventually speed up.
The Law of Acceleration and Mass
Newtons Second Law the Law of Acceleration and mass states " The acceleration of an object depends on the mass of the object and the amount of force applied." The amount of force needed to accelerate an object depends on the size or mass of the object. When an object is accelerated the object will go in the same direction as the net force that was applied. An objects acceleration increases when more force is applied on the object, but then again an objects acceleration decreases when the amount of force used is decreasing. For example if you where at a store with a hand held basket with items in it more force would be required to lift or accelerate the basket.
The Law of Action and Reaction
The Law of Action and Reaction states " Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first." The Law of Action and Reaction means that all forces act in pairs. The forces act in pairs because it makes up Action and Reaction. A force is always applied from one object to another. This rule is for all forces. Action and Reaction do not act on the same object. For example if a car is driving down a road at a fast speed and a car pulls in front is the action and the person driving that stops is the reaction.
