Biomechanics
Archimedes Principle
Propulsive forces
Propulsive Drag
Propulsive lift
Drag forces
Surface Drag
Wave drag
Form drag
Newton's Laws
Law of Inertia
Law of Acceleration
Law of Reaction
Levers
Longer the lever the greater the force
1st Class, 2nd Class, 3rd Class
Force Summation
Use as many body segments as possible
Sequential acceleration of body parts
Correct timing
Increase Range Of Motion
Stability and Balance
Widen Base of Support
Lower Centre of Gravity
Line of Gravity through Base of Support
Counter balance
Bigger Mass = more stable
Lean in
Increase co-efficient if friction
