A spring gun is described which is useful in experiments where an approximation of a point mass of known initial velocity is desired. The velocities imparted to a -in. steel ball range continuously to 12 m/sec and are reproducible to ±2%. The gun is of simple design, easily built in a departmental shop, and its dynamics readily understood. A brief description is given of uses which we have made of the gun both in instructional laboratories and in lecture demonstrations.
