MOTION: Simple harmonic motion (SHM)

A mass on a spring undergoes SHM. When the mass is at its maximum displacement from equilibrium, its instantaneous velocity:

Is maximum.

Cannot be determined from the information given.

Is less than maximum, but not zero.

Is zero.

When the length of a simple pendulum is tripled, the time for one complete vibration increases by a factor of:

1.7.

1.4.

Increasing the amplitude of a mass-and-spring system causes what kind of change in the resonant frequency of the system? (Assume no other changes in the system.)

The frequency increases.

The frequency depends on the displacement, not the amplitude.

The frequency decreases.

There is no change in the frequency.

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?

4 f.

0.25f.

0.5 f.

2 f.

A particle oscillates with undamped simple harmonic motion.

Which one of the following statements about the acceleration of the oscillating particle is true?

It is proportional to the frequency.

It is always in the opposite direction to its velocity

It is least when the speed is greatest.

It decreases as the potential energy increases
