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
