– Xochielt Sanchez

Answer by Robert Frost:

No, not a simple pendulum.  A simple pendulum needs gravity to accelerate it on the downward and decelerate it on the upward.  Here's a video of astronaut Don Pettit explaining this concept and showing a way to make a pendulum work in space by introducing a substitute for gravity.
