Intro to Harmonic Motion

Front

What is the formula to calculate frequency from the period of a wave?

Back

Frequency (f) is the reciprocal of the period (T): f = 1/T.

Front

If a wheel has a period of 2 seconds, what is its frequency?

Back

The frequency is 1/2 Hertz.

Front

What is simple harmonic motion (SHM)?

Back

Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement and acts in the opposite direction.

Front

Which of the following is an example of simple harmonic motion?

Back

A mass on a spring is an example of simple harmonic motion.

Front

What is the amplitude of a pendulum?

Back

The amplitude of a pendulum is the maximum angle from the vertical position.

Front

What does a wide swing of a pendulum indicate about its amplitude?

Back

A wide swing indicates a larger amplitude.

Front

What does a narrow swing of a pendulum indicate about its amplitude?

Back

A narrow swing indicates a smaller amplitude.

Front

How is the period of a pendulum related to its length?

Back

The period of a pendulum is directly related to the square root of its length: T = 2π√(L/g), where L is the length and g is the acceleration due to gravity.

Front

What is the relationship between frequency and period?

Back

Frequency is the number of cycles per second, while the period is the time taken for one complete cycle. They are inversely related.

Front

What is the frequency of a pendulum with a period of 2 seconds?

Back

The frequency is 1/2 Hertz.
