The lower the centre of gravity, the larger the base of support, the closer the line of gravity to the center of the base of support, and the greater the mass, the more STABILITY increases.

For this principle you will require a partner (someone at school or at home). Once you have established your position, have your partner push from the lateral side of your shoulder.

A.position yourself in a 3 point stance, with as low a centre of gravity as you can manage

B.stand with knees bent deeply, hands on your knees

C.stand straight with knees shoulder width apart

D.stand on one foot, arms extended outward

E.stand on one foot, the other foot extended forward with a straight knee

Respond to the following questions and submit the answers to your teacher:

1. Which position is the most stable? Explain why this might be.

2. Which position is the least stable? Explain why this might be.

3. Draw a diagram or take a photo to illustrate the positions in "A" "B" "C" "D" and "E".

4. What conclusion can you draw with respect to base of support and stability, centre of gravity and stability?

5. Give an example of an activity where you want to be more stable, less stable? Explain how stability is used to improve performance
