MOTION: Simple harmonic motion (SHM)

Curve B in the figure represents:

A moderately damped situation.

Critical damping.

An overdamped situation.

An underdamped situation.

A mass is attached to a vertical spring and bobs up and down between points A and B. Where is the mass located when its potential energy is a maximum?

One-fourth of the way between A and B

Midway between A and B

At either A or B

None is correct.

A mass m hanging on a spring has a natural frequency f. If the mass is increased to 4m, what is the new natural frequency?

0.5 f.

2 f.

4 f.

0.25f.

Increasing the spring constant k of a mass-and-spring system causes what kind of change in the resonant frequency of the system? (Assume no change in the system's mass m.)

The frequency increases.

The frequency decreases.

There is no change in the frequency.

The frequency increases if the ratio k/m is greater than or equal to 1 and decreases if the ratio k/m is less than 1.

Doubling only the spring constant of a vibrating mass-and-spring system produces what effect on the system's mechanical energy?

Increases the energy by a factor of two.

Increases the energy by a factor of three.

Increases he energy by a factor of four.

Produces no change.
