centre of gravity and balance Flashcards
1
Q
centre of gravity
A
the single point that moves in accordance with Newton’s simple laws of motion.
2
Q
upper legs of typical human constitute approx. what percentage of body mass
A
19.3%
3
Q
centre of gravity is centered between the 2 supports then
A
then the torques about the CofG due to reaction forces R1 and R2 are opposite and equal, and therefore cancel
4
Q
an object is balanced only when..
A
its CofG lies above the base area defined by its supports
5
Q
lower centre of gravity =
A
greater stability
6
Q
stable activity is when the centre of gravity
A
lies inside the area of support
7
Q
unstable activity is when the centre of gravity
A
where centre of gravity is outside of area of support
