Javelin Throw Distance

Hard
Javelin Throw Distance | Science Fair Projects | STEM Projects
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.
You will need a football field, 3 javelins, 3 athletes, 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.

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.
