Simple pendulum

Front

What is a simple pendulum?

Back

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

Front

What is the period of a pendulum?

Back

The period of a pendulum is the time it takes to complete one full back-and-forth swing.

Front

What factors affect the period of a simple pendulum?

Back

The period of a simple pendulum is affected by the length of the string and the acceleration due to gravity, but not by the mass of the bob.

Front

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

Back

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

Front

What is frequency in the context of a pendulum?

Back

Frequency is the number of complete oscillations or swings a pendulum makes in one second, measured in Hertz (Hz).

Front

How do you calculate the frequency of a pendulum?

Back

Frequency (f) can be calculated using the formula f = 1/T, where T is the period of the pendulum.

Front

What is the relationship between period and frequency?

Back

The period and frequency of a pendulum are inversely related; as the period increases, the frequency decreases and vice versa.

Front

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

Back

The unit of measurement for the period of a pendulum is the second (s).

Front

If a pendulum completes 42 oscillations in 1 minute, what is its frequency?

Back

The frequency is 0.7 Hz (42 oscillations/60 seconds).

Front

If a pendulum has a longer string, what can be said about its period?

Back

A pendulum with a longer string will have a longer period, meaning it takes more time to complete one full swing.
