- Astronomers study the gyration of planets around their stars.
- The dancer's hips moved in a hypnotic gyration.
Advanced Usage
- "Center of gyration": In mechanics, a point such that if the whole mass of a body were concentrated there, its moment of inertia would remain the same.
- "Radius of gyration": A measure of the distribution of an object's mass around an axis of rotation, crucial in structural engineering and physics.
