Stability

Question 1

What is centre of mass?

Answer 1

The point at which a body is balanced in all directions; the point from which weight appears to act

Question 2

What are the factors affecting centre of mass?

Answer 2

The location of the centre of mass depends on the distribution of body mass
Can be changed in sports to improve technique

Question 3

What is stability?

Answer 3

The ability of a body to resist motion and remain at rest
The ability of a body to withstand a force applied and return to its original position without damage

Question 4

What are the four factors that affect stability?

Answer 4

Mass of the body
Height of the centre of mass
Bass of support
Line of gravity

Question 5

How does mass of body affect stability?

Answer 5

The greater the mass of a body, the greater its inertia and therefore the greater its inertia

Question 6

How does height of the centre of mass affect stability?

Answer 6

The lower the centre of mass the more stable an object is

Question 7

How does base of support affect stability?

Answer 7

The greater size of the base of support the greater the stability
Can be increasing the distance between 2 points of contact or increasing the number of contact points

Question 8

Hotter does line of gravity affect stability?

Answer 8

The more central the line of gravity to the bass of support, the greater the stability
