Newton's Laws of Motion
By Andy Deering #Kettner #NewtonsLaws
Newton's First Law of Motion states that an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force.
-An object moving will stay moving at a constant velocity unless outside forces, such as friction and gravity, act upon it.
-An object at rest will stay at rest until unbalanced forces act upon it.
-The tendency to resist a change in motion is called inertia, the more mass an object has, the greater its inertia
Newton's Second Law of Motion states that the force of an object is equal to its mass multiplied by its acceleration (F=MA).
-The acceleration of an object depends on its mass, the more mass the harder it is to accelerate.
-A net force changes the velocity of an object, and causes it to accelerate.
Newton's Third Law of Motion states that for every action there is an equal and opposite reaction.
-The force exerted by the first object is the action force, and the force exerted by the second object is the reaction force.
-When one object exerts a force on another object, the second object exerts an equal force in the opposite direction.
