The term 'Olympics Projectiles' refers to the sport of Discus throwing, which is an event in the Olympic Games. Discus throwing involves athletes throwing a heavy disc-shaped object as far as possible. The discus is made of metal or plastic and is thrown from a circle with a 2.5 meter diameter. The athlete must stay within the circle while throwing the discus. Discus throwing has been part of the Olympics since 708 BC and is one of the oldest events in the Games.
