Centre Of Mass Flashcards
1
Q
Centre of mass or..
A
Centre of gravity
2
Q
Define centre of mass/gravity
A
The centre of mass/gravity of an object is the point through which all of its weight appears to act
3
Q
Where is a triangle’s centre of gravity?
A
Where the medians intersect is a triangle’s centre of gravity
4
Q
When will an object topple over?
A
An object will topple over when the line of action of its weight falls outside its base
5
Q
How can we make an object more stable?
How does this make the object more stable?
A
We can make an object more stable by:
- lowering its centre of gravity
- widening its base, increasing the base area
This ensures the object must tilt a lot for its weight to fall outside its base
