    1. MECHANICAL PRINCIPLES

    2. MECHANICAL PRINCIPLES STABILITY TRANSFER OF WEIGHT FORCE FRICTION LEVERS

    3. MECHANICAL PRINCIPLES STABILITY How stable you are depends on: Your BASE Your CENTRE OF GRAVITY

    4. MECHANICAL PRINCIPLES To make your body is more stable you should consider Lowering your C of G Making the area of your base larger Keeping C of G as close to centre of base as possible If there is an oncoming force- leaning into it

    5. MECHANICAL PRINCIPLES TRANSFER OF WEIGHT This is the movement of weight from one part of the body to another Throwing adds power Catching absorbs force Striking adds power Gymnastics allows movement

    6. MECHANICAL PRINCIPLES FORCE Newton’s 3rd.Law of Motion “For every action there is an equal reaction” If a force is applied in one direction the body will move in the opposite direction

    7. MECHANICAL PRINCIPLES FRICTION This is caused when 2 surfaces rub together Creates RESISTANCE Advantage V Disadvantage

    8. MECHANICAL PRINCIPLES LEVERS Levers are used to help move loads In the body lever = bone Fulcrum is usually a joint Load is the part of the body being moved plus any implement Effort is supplied by the muscle contracting and pulling on the tendon The longer the lever the faster its speed at the end
