Newton's First Law

Newton's 1st law states that an object will move with a constant velocity unless acted upon. This means that a object that is standing still will stay in place unless a force pushes on it. The concept of Inertia is the tendancy that and object stays at a constant velocity.

This applies to snowboading when a snowboarder drops into the half pipe. He accelerates until he reaches the bottom and his inertia carries him to the opposite side of the half pipe so that he can do his trick.

Newton's Second Law

Newton's 2nd law states that accelleration is produced when a force acts on a mass. This means that the greater the mass of the object, the more force needed to accelerate the object. If force is put on an object, it will accelerate in the opposite direction that the force is being put on.

Newtons second law applies to snowboarding when a snowboarder leans his body and the snowboard turns in the oppostie direction.

Newton's Third Law :)

Newton's 3rd law states that for every action there is an equal and opposite reaction. All forces are an interaction between two objects and whenever two things interact, there is a action and reaction force. An action and reaction forces act on each other in opposite directions.

Newtons Third Law applies when the snowboarder turns the board and digs it into the snow. The snow pushes back and stops the board from going further.
