Biomechanics

Question 1

Definition of centre of gravity

Answer 1

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

Question 2

Definition of balance

Answer 2

Balance is when the body is in a state of equilibrium, either when the body is at rest if whilst it is moving. Balance and equilibrium will occur when the body’s centre of gravity falls within the base of support

Question 3

Definition of stability

Answer 3

Stability is the ability to maintain on balance

Question 4

Definition of base of support

Answer 4

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

Question 5

What are the most stable positions?

Answer 5

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

Question 6

What are the most unstable positions?

Answer 6

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