Newton's Third Law of Motion

Whenever one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first.

Coriolis Force Motion on a Latitudinal Circle

Coriolis Force—the force per unit mass that results from the rotation of the earth and acts on a moving particle with respect to the earth to deviate it.

•      Perpendicular to the axis of rotation and the velocity vector.
•      Directed to the right (in the Northern Hemisphere) and radially outward from the axis of rotation. 
•      Can only change direction, not magnitude.

Components of the Coriolis force (CF) due to relative motion along a latitude circle. Ra is the apparent radius, Re is the radius of the earth., and omega is Earth's rotational frequency.

Newton's Three Laws of Motions

            Isaac Newton, the father of mechanics, is one of the most important scientists who ever lived, changing the standards by which scientists think today. His genius in mathematics and mechanics is exemplified by his creation of calculus to explain observations of the world around him. In addition, his laws of motion opened the door to progressive new thinking, enlightening the minds of thousands to the nature of things. His laws of motion make up the foundation for which dynamic meteorology exists.

1)    Law of Inertia—a body at rest or in motion will tend to stay that way until acted upon by a net external force.

2)    Law of Acceleration—a change in motion relates directly to a force trying to move it.

F = ma    or    F = ρg

3)    Action-Reaction Law—for every action there is an equal and opposite reaction.
