Question

In the given pendulum lab data, what effect does increasing the string length have on the period of the pendulum?

A) It decreases the period
B) It has no effect on the period
C) It increases the period
D) It makes the period irregular

Answer 1

Increasing the string length of a pendulum results in an increase of the pendulum's period, as the period of a simple pendulum is directly affected by its length and the acceleration due to gravity.

Step-by-step explanation:

In pendulum lab data, increasing the string length of a pendulum has the effect of increasing the period of the pendulum's swing. To illustrate, if you double the length of a pendulum, the period will increase. Conversely, if you decrease the length of the pendulum by 5.00%, the period will decrease, albeit not as drastically. This relationship is due to the fact that the period of a simple pendulum is primarily affected by its length and the acceleration due to gravity. The mass of the pendulum bob and the amplitude of the swing (provided the amplitude is not too large) have no significant effect on the period. Therefore, the correct answer to the question would be C) It increases the period.
