AIR TRACK ACCESSORIES

TEL 212 Spare Gliders
These gliders are designed for rugged use. They are tested by adding a mass equal to the glider mass to ensure that they float properly. Threaded grooves for #10-24 screws on the top and both sides of the glider’s vertical section allow additions to be made without drilling and tapping holes. They have nickel plated spring steel bumpers and fastening points for springs at each end. The mass of the glider is within 1 gm of its stated mass.
1 TEL 212G 150 gm Gold $42.00
2 TEL 212R 300 gm Red $48.00
3 TEL 212B 450 gm Blue $60.00

THESE ACCESSORIES WILL FIT BOTH THE TWO METER AND BASIC AIR TRACK

TEL 214 End Pulley
This lightweight, low-friction pulley mountson a modified end-stop to guide a string over the end of the air track. Connecting the string to a glider allows acceleration experiments with a constant force.
5 TEL 214 $61.00



TEL 215 Air Pulley
Using the same principle as the air track, this pulley assembly gives a friction-free method of attaching weights to the glider. Weights of up to 50 gm are held by a piece of mylar tape. With the Air Pulley there is no angular momentum to complicate the analysis of motion.
6 TEL 215 $203.00



TEL 216 Instantaneous Velocity Flags
Four aluminum flags (one each 5cm, 10cm, 20cm, 30cm) can be mounted on a glider to measure the velocity of an accelerating glider through a photogate thus making it possible to extrapolate the true velocity of the glider at the gate.
7 TEL 216 $99.00



TEL 217 Inelastic Collision Kit
The principle of conservation of momentum can be demonstrated with this kit. Four replacement Velcro® bumpers replace the normal bumper springs. The Velcro® causes colliding gliders to stick together.
8 TEL 217 $20.00



TEL 219A Glider Bumper Springs
Set of 20 nickel plated spring steel bumper springs to replace broken springs that become damaged.
9 TEL 219A $62.00



TEL 219B Soft Bumper Springs
For “softer” collisions use these springs to replace the standard bumper springs that come with the unit. Comes in sets of 20.
10 TEL 219B $95.00



TEL 220 Coil Springs
These coil springs come in sets of 10. They can be used for harmonic motion studies on an air track. If used to hang small masses (10-100gm), the set makes an harmonic motion experiment on its own. Springs are wound stainless steel wire 0.5mm in diameter and will stretch to 10 times their length without damage.
2.5 cm Coil Spring
Force constant 3.2 Newtons/meter
11 TEL 220A $42.00
5.0 cm Coil Spring
Force constant 2.5 Newtons/meter
12 TEL 220B $50.00
7.5 cm Coil Spring
Force constant 1.8 Newtons/meter
13 TEL 220C $56.00



TEL 221 Riser Block Kit
Four 4 cm square aluminum blocks with thicknesses of 0.3, 0.6, 1.3, and 2.6 cm are included. These blocks can be stacked to provide a fixed and reproducible slope when doing inclined track experiments.
14 TEL 221 $19.00



TEL 222 Ceramic Magnet Set
A set of 10 magnets which can be attached to the top of a glider for non-contact collisions or taped to the skirt of a glider for damping in harmonic motion experiments.
15 TEL 222 $8.00
