# Javelin Throw Distance

Hard
Ever wondered how far you can throw a javelin? Test different angles and measure the distance to find out!

## Hypothesis

The hypothesis is that the javelin will travel the furthest when thrown at 45°.

## Method & Materials

You will need to set up a football field, get 3 javelins, 3 athletes trained in javelin throws, a 100 meter measuring tape, a DVD video-recorder, a DVD disc, a portable DVD player with screen, an assistant, a cameraman, and a protractor. The athletes will attempt 5 throws each at 20°, 25°, 30°, 35°, 40° and 45° angles.

## Results

The results showed that the distance achieved for each javelin throw peaked at the release angle of 35°. This was true for all 3 athletes. The hypothesis that the javelin will travel the furthest when thrown at 45° was proven to be incorrect.

## Why do this project?

This science project is interesting because it tests a very old athletic event that has been around since the 8th century. It also tests the aerodynamics and biomechanical principles involved in javelin throwing.

## Also Consider

Variations of this experiment could include repeating it with a discus and shot putt, or repeating it with athletes of different heights.
