A spring is hanging motionless from the ceiling of a room on theearth. You attach a mass to the end of the spring and afterreleasing the mass, you observe that the spring extends adistance  before momentarily coming to a halt. What thenmust be the distance below just the spring's equilibrium positionto the new equilibrium position of the spring-mass system?

	A.
	B.
	C.
	D.

A spring is hanging downward from the ceiling of a room on theearth, has nothing attached to the end, and is motionless. Is thespring in equilibrium?

	A.	Yes.
	B.	Unable to determine without more information.
	C.	There must be a mass on the end of the spring.
	D.	No.

For an object moving under simple harmonic motion while attachedto a spring, when is the speed the greatest?

	A.	When there is maximum displacement from equilibrium .
	B.	When the velocity is a minimum.
	C.	When there is no displacement from equilibrium .
	D.	Only when the object on the spring is not hanging down due togravity.

A block is attached to a spring and is hanging downwardmotionless from the ceiling of a room on the earth. Is the springin equilibrium?

	A.	No.
	B.	Unable to determine without more information.
	C.	Yes.
	D.	We need to know the mass of the block.

For an object moving under simple harmonic motion while attachedto a spring, when is the net force the greatest?

	A.	When there is no displacement from equilibrium.
	B.	When the velocity is a maximum.
	C.	Only when the object on the spring is not hanging down due togravity.
	D.	When there is maximum displacement from equilibrium.

For an object moving under simple harmonic motion while attachedto a spring, when is the net force zero?

	A.	Only when the object on the spring is not hanging down due togravity.
	B.	When the velocity is a minimum.
	C.	When there is no displacement from equilibrium.
	D.	When there is maximum displacement from equilibrium.

What is the term for the object's maximum possible displacementwhen moving under simple harmonic motion?

	A.	Amplitude of velocity.
	B.	Amplitude of displacement.
	C.	There is no term for this situation.
	D.	Amplitude of acceleration.

If at a certain point in time the displacement is positive foran object moving under simple harmonic motion, what is the sign ofits acceleration?

	A.	Positive.
	B.	Negative.
	C.	Can not be determined.
	D.	Depends if the object is moving positively or negatively.

For an object moving under simple harmonic motion while attachedto a spring, when is the speed zero?
