Projectile Launcher

An ideal piece of apparatus for investigating the motion of projectiles. The apparatus can easily be clamped to a bench/desk (clamp provided) and the angle of projection can easily be adjusted through 90°. The angle is read by means of a plumb line that hangs past an angle measurer that is attached to the unit. Firing of the unit is obtained by releasing a spring-loaded rod that acts against a large ball bearing (included).
