Question

Select the correct answer.
Galileo’s pendulum theory stated that the time taken to swing through one complete cycle of a pendulum depends on what?
A.
the mass tied to it
B.
the amplitude of the swing
C.
the length of the string
D.
the velocity of the pendulum
E.
the volume of the mass tied

Answer 1

The correct answer is: **C. the length of the string**.

Galileo discovered that the period of a simple pendulum (the time taken to complete one full swing back and forth) is primarily dependent on the length of the pendulum and not on the mass of the bob or the amplitude of the swing (as long as the amplitude is small).
