shape
Where will be the centre of gravity of a uniform rod lies ?
At its end
At its middle point
At its centre of its cross sectional area
Depends upon its material

pendulum
gauge
What is one way you might increase the stability of an object?
Lower the center of gravity
Raise the center of gravity
Increase the height of the object
Shorten the base of the object
Where do you hang the plumb line when determining the CG?
It doesn't matter, because it always goes through the CG
Only from the corners
From the point where you are suspending the object
At the right angle
