Biomechanical Principles and Levers


Newton's Laws: 

1st Law - Inertia 

A body continues in a state of rest or uniform velocity unless acted upon by an external or unbalanced force 

E.g. A golf ball will remain still unless the force applied by a golf club will continue to move at a constant velocity unless a force acts on it to slow it down or changes its direction

2nd Law - Acceleration 

A body's rate of change of momentum is proportional to the size of the force applied and acts in the same direction as the force applied

E.g. When a golf ball…
