Simple pendulum

Front

What is a simple pendulum?

Back

A simple pendulum consists of a mass (the bob) attached to a string or rod of fixed length that swings back and forth under the influence of gravity.

Front

What is the formula for the period of a simple pendulum?

Back

The period (T) of a simple pendulum is given by the formula T = 2π√(L/g), where L is the length of the pendulum and g is the acceleration due to gravity.

Front

What is the unit of measurement for the period of a pendulum?

Back

The unit for the period of a pendulum is seconds.

Front

What is the relationship between period and frequency?

Back

Frequency (f) is the reciprocal of the period (T). f = 1/T. If the period is long, the frequency is low, and vice versa.

Front

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

Back

The frequency is 0.5 Hz (f = 1/T = 1/2).

Front

Does the mass of the pendulum affect its period?

Back

No, the mass of the pendulum does not affect its period; only the length of the pendulum and the acceleration due to gravity do.

Front

What factors affect the period of a simple pendulum?

Back

The period of a simple pendulum is affected by the length of the pendulum and the acceleration due to gravity.

Front

Which pendulum will have a longer period: a 1.0 m pendulum or a 0.5 m pendulum?

Back

The 1.0 m pendulum will have a longer period.

Front

What is the period of a pendulum that is 0.25 m long?

Back

The period is approximately 0.5 seconds.

Front

True or False: The time for a complete back-and-forth swing of a pendulum is its frequency.

Back

False. The time for a complete swing is the period.
