The Center of Gravity and Stability

True-False Quiz

Please answer the following questions


1	The center of gravity is the point where all of the weight of the body or object is concentrated.
		A)	True
		B)	False


2	Stable equilibrium occurs when an object is placed in such a fashion that an effort to disturb it would require its center of gravity to be raised.
		A)	True
		B)	False


3	Unstable equilibrium exists when it takes only a slight push to destroy it.
		A)	True
		B)	False


4	Neutral equilibrium exists when an object's center of gravity is lowered when it is disturbed.
		A)	True
		B)	False


5	The mass or weight of an object is a factor in equilibrium only when motion or an external force is involved.
		A)	True
		B)	False


6	Greater stability is obtained if the base is support is narrowed in the direction of the line of force.
		A)	True
		B)	False


7	Other things being equal, the greater the mass of a body, the greater will be its stability.
		A)	True
		B)	False


8	For maximum stability, the line of gravity should intersect the base of support at a point that will allow the greatest range of movement within the area of the base in the direction of forces causing motion.
		A)	True
		B)	False


9	During the normal standing position, the center of gravity in an adult human being is located approximately at the level of the upper third of the sacrum.
		A)	True
		B)	False


10	When the external force acting on a body is lateral, stability is increased if the line of gravity is placed so that it will continue to remain over the base even when forced to move by the external force.
		A)	True
		B)	False
