Precision Air Track 1.5m, Daedalon®

With a Daedalon air track, you can present most of the principles of dynamics on one sturdy, easy-to-use and friction-free track. Students can examine the conservation of momentum by measuring the velocity of two gliders both before and after collision. Students measure the speed of the gliders using photogates, spark recording or an ultrasonic measurement system. These systems can be chosen as accessories (not included). Gliders come in three sizes, permitting students to study both equal and unequal mass collisions. By replacing the standard bumper springs on the gliders with Velcro bumper springs, a collision becomes inelastic. Riser blocks stacked under a track provide the inclined plane to study acceleration. The included pulley demonstrates acceleration under a constant force. Magnets attached to the gliders provide magnetic repulsion. The spring kit allows lab groups to study harmonic motion. Included with each track kit is a full instruction manual, which details not only how to set up and use the track, but also includes set up instructions and sample data for instructors. Daedalon air tracks are constructed using custom designed aluminum extrusion of hollow triangular cross section. Air feeds into one end of the closed extrusion and escapes through four rows of 0.9 mm diameter air holes drilled along the length of the track. The escaping air provides virtually friction-free support for the aluminum gliders, which fit over the outside surface of the track. A full-length metric tape is set into the extrusion and a guide groove for spark paper on the other side.
