• 14:5714:57, 14 January 2015 diff hist 0 m Radius of gyration Changed "mass, M" to "mass, m" to agree with Moment of Inertia page
• 14:5514:55, 14 January 2015 diff hist +25 m Radius of gyration Corrected to show equivalent mass between object(s) and point mass.
• 14:2014:20, 14 January 2015 diff hist +2 Spring (device) Corrected grammar. "commonest" -> "most common"
• 14:1214:12, 14 January 2015 diff hist +23 m Radius of gyration Added links (mass moment of inertia, point mass)
• 14:1014:10, 14 January 2015 diff hist +48 Radius of gyration The original phrase, "perpendicular distance from axis of rotation to center of gravity" was wrong. The phrase, "perpendicular distance from axis of rotation to point mass giving equivalent inertia" is closer to the truth.
