Question

If a pendulum is shortened, does its period increase or decrease?

a) Increase
b) Decrease
c) Remain the same
d) It depends on the mass of the pendulum bob

Answer 1

The period of a pendulum decreases when it is shortened.

Step-by-step explanation:

In a simple pendulum, the period is the time it takes for the pendulum to complete one full swing. The period of a simple pendulum depends on its length. When the length of a pendulum is shortened, its period decreases. Conversely, when the length of a pendulum is increased, its period increases.

For example, if you double the length of a pendulum, its period will also double. On the other hand, if you decrease the length of a pendulum by 5.00%, its period will decrease by the same percentage.

To summarize, when a pendulum is shortened, its period decreases.
