Biomechanics: Centre of Mass and Stability Flashcards
1
Q
Define centre of mass
A
The point of balance of a body
2
Q
Define stability
A
The ability to maintain a centre of mass over a base of support
3
Q
Define line of gravity
A
The line extending vertically downwards from the centre of mass
4
Q
Name 4 factors that affect stability
A
- Height of centre of mass
- Area of base of support
- Line of gravity
- Mass
5
Q
Explain how height of centre of mass affects stability
A
The lower the centre of mass, the greater the stability.
6
Q
Explain how the area of base of support affects stability
A
The more contact points, the wider/greater the base of support and the greater the stability.
7
Q
Explain how line of gravity affects stability
A
The closer the line of gravity is to the base of support, the greater the stability
8
Q
Explain how mass affects stability
A
The greater the mass of the object/performer, the greater the stability.
