Archery Range

This simulation shows how projectiles fall and drift on the way to a target. Pulling the string left adds power and pulling it down raises the aim. The arrow drops under gravity, slows with optional air drag, and is pushed sideways by an adjustable crosswind from minus 15 to 15 meters per second. Readouts show draw and speed, aim elevation, last arrow, score and crosswind. Three camera views let students watch from the side, behind the archer or at the target. Teachers can use it for projectile motion and vectors.

• Drag the string back and down, then release, and check the Draw and speed readout.
• Aim directly at the gold once and see how far the arrow lands below it.
• Change Crosswind to 10 meters per second and adjust your aim to hit the center.
• Turn off Air drag and compare where arrows land at full draw.
• Use Pull arrows to clear the target and try for a higher Score across six arrows.

1. 1Explain why an arrow must be aimed above the target.
2. 2Calculate that drop equals one half g times time squared.
3. 3Describe how a crosswind adds a sideways motion to a projectile.
4. 4Adjust aim using feedback from each shot.
