Centrifugal force serves as a reaction force to centripetal force, which is the force needed to move an object in a circle at constant speed. According to Newton's first law of motion, a moving body travels along a straight path with constant speed unless it is acted on by an outside force.
There has always been a lot of speculation over why Vincent Van Gogh cut off his ear. While there are different theories floating around for the reason, the most accepted reason believes that he cut off ear during a seizure of epilepsy. Paul Gauguin and Vincent Van Gogh were friends.
The evening before Van Gogh cut off his ear, he and Gauguin were sitting a cafÃ© drinking absinthe. Without any provocation, Van Gogh threw his absinthe at Gauguin. However, he did not remember the incident the next day. Gauguin informed him that he was going to move out, and this upset Van Gogh quite a bit.
