Mechanics 2: Centre of Mass
Cards in this deck (8)
- 1The centre of mass of a triangle with vertices at (x\(_1\), y\(_1\)), (x\(_2\), y\(_2\)) and (x\(_3\), y\(_3\))(\(\frac{x_1+x_2+x_3}{3}\) , \(\frac{y_1+y_2+y_3}{3}\))
- 2The centre of mass of a triangle lies ... of the way along a median?\(\frac{2}{3}\)
- 3In right-angled triangles the centre of mass is ... of the way from the right angle in both directions?\(\frac{1}{3}\)
- 4The centre of mass is...The point that the weight of an object can be thought of as acting at.
- 5The centre of mass of an object will lie on a line of ... of a shapeSymmetry
- 6To work out the centre of mass of composite bodies...1) Find the centre of mass of each part
2) Take moments around a point - 7A shape will topple if...The centre of mass is no longer above the base of the bottom edge
- 8If a lamina is hung freely from a pivot the centre of mass will be...Directly below the pivot
