{{Main article|Helicopter}}
The main rotor of a helicopter acts like a gyroscope. Its motion is influenced by the principle of gyroscopic precession which is the concept that a force applied to a spinning object will have a maximum reaction approximately 90 degrees later. The reaction may differ from 90 degrees when other stronger forces are in play.<ref>{{Cite web|title=Learning Center Courses Content - FAA - FAASTeam - FAASafety.gov|url=https://www.faasafety.gov/gslac/alc/course_content_popup.aspx?cID=104&sID=449|access-date=23 April 2021|website=Faasafety.gov|archive-date=20 April 2021|archive-url=https://web.archive.org/web/20210420152225/https://www.faasafety.gov/gslac/alc/course_content_popup.aspx?cID=104&sID=449|url-status=live}}</ref> To change direction, helicopters must adjust the pitch angle and the angle of attack.<ref>{{Cite web|title=Gyroscopic Precession|url=https://blog.aopa.org/aopa/2012/01/29/gyroscopic-precession/|website=Blog.aopa.org|date=11 October 2020|access-date=23 April 2021|language=en-US|archive-date=21 April 2021|archive-url=https://web.archive.org/web/20210421090846/https://blog.aopa.org/aopa/2012/01/29/gyroscopic-precession/|url-status=live}}</ref>
