Understanding Oscillatory Motion

What is the frequency of an oscillating body that makes 300 complete oscillations in half a minute?

• 5 Hz

• 20 Hz

• 15 Hz

• 10 Hz

Calculate the periodic time of an oscillating body with a frequency of 10 Hz.

• 0.2 seconds

• 0.5 seconds

• 1 second

• 0.1 seconds

If the periodic time is 0.1 seconds, what is the frequency?

• 0.5 Hz

• 10 Hz

• 20 Hz

• 5 Hz

Define amplitude in the context of oscillatory motion.

• Amplitude is the total energy of the oscillating system.

• Amplitude refers to the frequency of the oscillation.

• Amplitude is the maximum displacement from the equilibrium position in oscillatory motion.

• Amplitude is the average speed of oscillation.

What is the relationship between periodic time and time of amplitude?

• The periodic time is equal to the time of amplitude.

• The periodic time is twice the time of amplitude.

• The periodic time is three times the time of amplitude.

• The periodic time is half the time of amplitude.

If a pendulum has a periodic time of 2 seconds, what is the time of amplitude?

• Amplitude can be measured in seconds.

• The amplitude is half the periodic time.

• Amplitude does not have a time value.

• Amplitude is 2 seconds long.

How do you calculate the frequency from the number of oscillations and time?

• frequency = number of oscillations / time

• frequency = time / number of oscillations

• frequency = time - number of oscillations

• frequency = number of oscillations + time

What is the unit of frequency?

• Decibels (dB)

• Hertz (Hz)

• Watts (W)

• Joules (J)

Explain the significance of amplitude in oscillatory motion.

• Amplitude is irrelevant to the energy of oscillatory motion.

• Amplitude determines the frequency of oscillatory motion.

• Amplitude is significant as it indicates the energy and intensity of oscillatory motion.

• Amplitude only affects the direction of oscillatory motion.

If a pendulum completes 60 oscillations in 1 minute, what is its frequency?

• 1 Hz

• 30 Hz

• 2 Hz

• 0.5 Hz
