As projectile launchers are used, the projectiles (balls) may transfer some dirt to the inner surface of the barrel. The design of the launchers depend on a close fit between the ball and the barrel, so any additional material will cause friction and...
If you are not getting consistent launch speeds for a specific launch angle and range setting, check the following:
- Be certain the projectile ball is pushed back and seated against the air port before launch.

When using the Time of Flight Pad with the Vernier Projectile Launcher or Go Direct Projectile Launcher, each successful launch that hits the pad will show 6 events (3 blocked and 3 unblocked) in the data table. If that is not happening, check the fo...
