centre of mass

Question 1

define centre of mass

Answer 1

the ppoint at which the distribution of mass is equal in all directions

can also be defined as the point of balance

Question 2

what are the factors that affect stability

Answer 2

1. the height of the centre of mass
2. position of the line of gravity
3. area of the support base
4. mass of the performer

Question 3

how can we alter the factors affecting stability to increase stability

Answer 3

1. the lower the centre of mass - the greater the stability
2. the further the line of gravity from the central position the less stability
3. the wider the support base the greater the stability
4. the larger the mass of the performer - the greater the inertia and therefore the greater the stability
