Vibration Quiz

What is vibration?

• A constant, unchanging motion of an object

• The repetitive motion of an object around an equilibrium position

• A random movement of particles in a fluid

• The movement of sound waves through a vacuum

One vibration indicated by….

• B - A - C

• B - A - C - A -B

• B - A - C - A - B - A

• B - A - C - A

What is amplitude in the context of vibration?

• The number of oscillations per second

• The time taken for one complete cycle of vibration

• The maximum displacement of an object from its equilibrium position

• The rate at which energy is lost in a vibrating system

What is the period of vibration?

• The time taken for one complete cycle of vibration

• The distance between two peaks in a wave

• The maximum displacement of an object from equilibrium

• The number of vibrations occurring per second

What is the meaning of frequency in vibration?

• The time taken for one complete oscillation

• The number of oscillations occurring in one second

• The maximum energy of a vibrating system

• The distance a wave travels in one cycle

What is the unit of measurement for frequency?

• Newton (N)

• Second (s)

• Hertz (Hz)

• times

The period depends on amplitude.

• True

• False

A pendulum swings 8 times (n) in 10 seconds (t). What is the frequency of the swing?

• 0.8 Hz

• 0.8 s

• 1.25 Hz

• 1.25 s

If the number of vibrations is denoted by n and time is denoted by t, what is the formula to find frequency?

• f = n/t

• f = t/n

If the formula for the period is t/n, find the period of a pendulum that swings 20 times in 4 seconds.

• 5 s

• ⅕ s

• 5 Hz

• ⅕ Hz
