Question 1

Stability

Answer 1

the degree to which a body resists changing it’s equilibrium

Question 2

Balance

Answer 2

the ability to control the state of equilibrium

Question 3

how to increase stability and balance

Answer 3

Lower centre of gravity

Increase the size of the base of support

Ensure the line of gravity is over the base of support

Increase the friction between two or more bodies

Question 4

example of increasing stability and balance

Answer 4

in order to increase stability and maintain balance, the surfer lowers there knees, widens their base of support by widening their stance on the board and ensures their line of gravity remains within their Base of support

Question 5

example of of reducing stability and balance

Answer 5

The sprinter will reduce their stability by raising their centre of gravity and shifting their line of gravity to the very front edge of their base and support, this enables a faster start
