What happens to the period of a simple pendulum motion when it is in orbit inside the international space station?

a. the period will decrease.
b. the period will increase.
c. the period will not change.
d. the pendulum will not oscillate.

To solve this problem we will apply the concepts related to the simple harmonic movement referring to the period of a spring system.

The period is defined as

Where,

m = Mass

k = Spring Constant

As the system does not depend on the effect of gravity, but on the constant of the spring and mass, we can define that the period will not change. The correct answer is C.
