Vibrations and Simple Harmonic Motion

Which of the following is not an example of observed periodic motion?

• a car driving down a straight road
• the rotation of a wheel
• a playground swing
• ocean waves

The "period" is

• the time that it takes a complete cycle or wave oscillation to occur.

• the number of cycles or vibrations per unit of time.

• the rate of vibration within a wave pattern.

For a system in simple harmonic motion, which of the following is the time required to complete a cycle of motion?

• amplitude
• period
• frequency
• revolution

Amplitude

• The distance from any point on a wave to an identical point on the new wave

• The maximum distance that the particles of a wave's medium vibrate from their rest position

• The highest point on a wave

What property of the wave is represented by the letter "B"?

• amplitude
• crest
• trough
• wavelength

Oscillatory motion is also considered as

• non periodic motion

• periodic motion

• circular motion

In simple harmonic motion (SHM)...

• amplitude is dependent on period but not on frequency

• period is independent of amplitude

• frequency is independent of amplitude

• period and frequency is independent of amplitude.

The period of a pendulum may be decreased by

• Increasing the mass of the bob
• moving the equilibrium point
• decreasing the mass of the bob
• shortening the length of pendulum

The graph shows the reducing amplitude of a body in SHM. This is known as

• dumping

• damping

• wetting

• doodling

A pendulum oscillates as shown. At which of the following positions is the kinetic energy equal to the total energy?

• A

• B

• C
