Athletics at the 1964 Summer Olympics – Men's high jump set a new Olympic record with 2.18 metres. Jumpers had to pass 2.06 metres to qualify for the final. The bar started at 1.90 metres, increasing gradually to 2.06 metres. Each jumper had three attempts at each height or could skip any lower height (but could not return to a lower height if he determined that he could not succeed). Each jumper again had three attempts at each height, with the bar starting at 1.90 metres. Three jumpers were unable to perform as well as they had in the qualification.

Center of mass similar, e.g., Pluto and Charon, the barycenter will fall outside both bodies. When high jumpers perform a "Fosbury Flop", they bend their respective bodies in such a way that they clear the bar while their respective centers of mass do not necessarily do so. Because it is the height of the center of gravity (rather than of the highest part of the body) that constrains the minimum energy investment for "clearing" the bar, "snaking over" the bar can reduce the energy expended in propelling the body upward. In kinesiology and biomechanics, the center of mass is an important parameter that
