Physics Review: Ch. 11 Vibrations and Waves

Which of the following is not an example of approximate simple harmonic motion?

• a ball bouncing on the floor

• a child swinging on a swing

• a piano wire that has been struck

• a car’s radio antenna waving back and forth

A mass attached to a spring vibrates back and forth. At the equilibrium position, the

• acceleration reaches a maximum.

• velocity reaches a maximum.

• net force reaches a maximum.

• velocity reaches zero.

A simple pendulum, swings in simple harmonic motion. At maximum displacement,

• the acceleration reaches a maximum.

• the velocity reaches a maximum.

• the acceleration reaches zero.

• the restoring force reaches zero.

The angle between the string of a pendulum at its equilibrium position and at its maximum displacement is the pendulum’s

• period.

• frequency.

• vibration.

• amplitude.

For a mass hanging from a spring, the maximum displacement the spring is stretched or compressed from its equilibrium position is the system’s

• amplitude.

• period.

• frequency.

• acceleration.

A wave travels through a medium. As the wave passes, the particles of the medium vibrate in a direction perpendicular to the direction of the wave’s motion. The wave is

• longitudinal.

• a pulse.

• electromagnetic.

• transverse.

One end of a taut rope is fixed to a post. What type of wave is produced if the free end is quickly raised and lowered one time?

• pulse wave

• periodic wave

• sine wave

• longitudinal wave
