True-False Quiz

Please answer the following questions


1	The basic joint actions in pushing and pulling patterns of motion are flexion and extension.
		A)	True
		B)	False


2	A push, pull, or lift is always applied directly to an object.
		A)	True
		B)	False


3	All joint motions occur at the same time or very near the same time.
		A)	True
		B)	False


4	However motion is given, it always involves the imparting of force.
		A)	True
		B)	False


5	A punch is usually directed horizontally rather than vertically.
		A)	True
		B)	False


6	For an efficient lift, one must first establish the location of the axis of rotation for the lift.
		A)	True
		B)	False


7	The principle involved in lifting is that of minimizing the resistance arm of a lever to reduce the amount of effort needed to lift a given weight.
		A)	True
		B)	False


8	Relating to the magnitude of force, for maximum accuracy, the largest possible number of segments should be used through the smallest possible range of motion.
		A)	True
		B)	False


9	If an object is free to move only along a predetermined path, any component of force not in the direction of this pathway is wasted and may serve to increase friction.
		A)	True
		B)	False


10	If the force applied to a freely movable object is not in line with the latter's center of gravity, it will result in rotary motion of the object.
		A)	True
		B)	False
