biomechanics

Question 1

what is the centre of gravity / mass

Answer 1

the point through which the entire mass of the body may be considered to act

Question 2

does the centre of mass change

Answer 2

yes, it changes position as the body changes shape

Question 3

what is balance

Answer 3

• when the body is in a state of equilibrium

- when the body is at rest or whilst it is moving

Question 4

when do balance and equilibrium occur

Answer 4

they occur when the body’s centre of gravity falls with the base of support

Question 5

what is the line of gravity

Answer 5

• a theoretical line that is drawn from the centre of gravity directly to the floor
• if the line of gravity falls inline with the base of support the body is in balance

Question 6

is the formula for determining wether the body is on balance always effective

Answer 6

no, the formula isn’t always perfect and can sometimes be incorrect

Question 7

what is stability

Answer 7

the ability to maintain balance

Question 8

what is the most stable position

Answer 8

when the base of support is large and the centre of gravity is low

Question 9

what is the most unstable position

Answer 9

when the base of support is small and the centre of gravity is high

Question 10

what is the base of support

Answer 10

the area of ground bounded by the points of the body in contact with the floor
