Impact

True-False Quiz

Please answer the following questions


1	The three problems in receiving the impact of external objects include maintaining equilibrium.
		A)	True
		B)	False


2	The more gradual the loss of momentum of the moving body, the greater the force exerted on the body.
		A)	True
		B)	False


3	The larger the area receiving the impact, the less will be the force per unit of the surface area.
		A)	True
		B)	False


4	At the moment of impact, the line of gravity should be centered above the base.
		A)	True
		B)	False


5	The more gradually the velocity of an external object is reduced, the more likely is the object to rebound when its impact is received.
		A)	True
		B)	False


6	Other things being equal, the larger the base of support in the direction of the impetus, the greater will be the body's equilibrium.
		A)	True
		B)	False


7	The reduction in momentum of any object can be accomplished by an equivalent product combination of force and gravity.
		A)	True
		B)	False


8	If the line of flight of an external object is perpendicular to the outstretched arm, the torque is the product of the force of impact and length of the arm.
		A)	True
		B)	False


9	Avoidance of injury in catching or receiving external forces is achieved by decreasing the distance over which the object's kinetic energy is lost.
		A)	True
		B)	False


10	Catching an external object with accuracy and control depends largely on the position of the catcher relative to the direction of the approaching object.
		A)	True
		B)	False
