Question

1. Which one of the following statements concerning Simple HarmonicMotion (SHM) is TRUE?

a. SHM occurs whenever an object isdisplaced from a position of stable equilibrium andreleased.
b. SHM occurswhenever an object is displaced from a position of unstableequilibrium and released.
c. SHM occurs whenever an object is acted upon by arestoring force that is proportional to the displacement from aposition of stable equilibrium.

2. Which one of the following statements concerning the magnitudeof the acceleration of an object undergoing SHM isTRUE?

a. The acceleration is alwayszero.
b. The acceleration iszero when the object passes through the equilibriumposition.
c. Theacceleration is zero when the object is at maximum displacementfrom equilibrium.

3. Consider a mass-spring system undergoing SHM. Which one of thefollowing statements is correct concerning the dependence of theperiod of the motion on the mass that is attached to thespring?

a. If the mass is doubled, the periodwill be half the original.
b. If the mass is doubled, the period will be about70% of the original.
c. If the mass is doubled, the period will be about1.4 times the original.
d. If the mass is doubled, the period will be double theoriginal. Which one of the following statements concerning the magnitudeof the acceleration of an object undergoing SHM isTRUE?

a. The acceleration is alwayszero.
b. The acceleration iszero when the object passes through the equilibriumposition.
c. Theacceleration is zero when the object is at maximum displacementfrom equilibrium.
