        Rotations in Space

        This interactive activity adapted from NASA demonstrates how different objects rotate in space and addresses related questions such as what causes rotation and why objects in space rotate. In three short videos, astronaut Jeffrey Williams, onboard the International Space Station, spins different objects (a tin can, a hammer, and a can opener), observes their behavior, and explains each one's response to rotational force. Activity screens provide illustrations to define key concepts, such as microgravity, center of gravity, translation, and torque, and to examine rotation in the context of the Moon and spacecraft.
