Overview
This 'experiment' mode allows you to work backwards. If you know where your projectile landed and at what angle it was fired, you can find out how fast it was moving initially.
💡
Pro Tips
Ensure you measure distance from the point directly below the launch position.
Angle can be measured using a clinometer or protractor on the launcher.
This model assumes no air resistance (vacuum conditions).

Fun Facts
"In lab settings, spring-loaded launchers are used to provide consistent initial velocity."
"The landing point is often marked using carbon paper or sand pits."
"Discrepancies from theory are often due to air drag or spin (Magnus effect)."
