Abstract

To understand the process of generating the speed of the discus relative to the center of mass (c.m) of the thrower+discus system, we will need to look at the angular momentum of the thrower, the angular momentum of the discus and the angular momentum of the combined thrower+discus system. Although the discus speed is the ultimate goal, one cannot look exclusively on the raw speeds because speed alone does not explain the dynamic relationships between the speed of the discus, the forces made by the thrower on the ground and the motions of the thrower. Essentially, the angular momentum of the thrower+discus system is equal to the to the angular momentum of the thrower plus the angular momentum of the discus. In other words, the angular momentum of the discus is directly proportional to its speed. By focusing on angular momentum instead of speed, one can gain a mechanical understanding of the discus speed development process, because the angular momentum of the discus is pretty much directly proportional to its speed.
