Javelin take-off angle and throw distance Featured science projectScience project video


The hypothesis that the javelin will travel the furthest when thrown at 45°is proven to be incorrect. Our results show that the optimal take-off angle is 35°.

Javelin throwing is a very old athletic event. It was mentioned as early as the 8th century,  in The Iliad, a literature piece written by Homer. Javelin throwing was also contested in the ancient Olympic games held in Greece. Currently, javelin throwing is one of the regular events contested in track and field events all over the world. In these events, participants use a 2.5 meter long javelin.

The science fair project can also be repeated with a discus and shot putt.

Try to repeat the experiment on athletes of different heights.
