Question

1. For an object undergoing simple harmonic motion,

A. the amplitudes are usually regarded as being large

B. the acceleration is greatest when the displacement is greatest.

C. the acceleration is greatest when the speed is greatest.

D. the maximum potential energy is larger than the maximum kinetic energy.

E. the displacement is greatest when the speed is greatest.

2. If both the mass m of a simple pendulum and its length L are doubled, the period will

A. increase by a factor of 1.4

B. increase by a factor of 2.

C. increase by a factor of 0.71.

D. be unchanged.

E. increase by a factor of 4.

3. Consider a mass hanging vertically from a spring and at equilibrium. If you pull it down by 2

cm and release it, it begins to oscillate at a frequency f1. If you had pulled it down instead by 4

cm, what would its frequency of oscillation be? Assume simple harmonic motion.

A. f1

B. (2)*f1

C. 2f1.

D. 4f1.

E. None of the above
