- Page 2 Air track Composition DM241013 - Air track + accessories 1 aluminium track, 1.85 m long, with scale and adjustable feet 2 plastic gliders (45 g) 10 additional 5 g masses 1 hook accessory for accelerometer (0.8 g) 1 spring accessory for elastic collisions (0.7 g)
- Page 3 Description This apparatus allows single-direction motion to be studied whilst virtually eliminating friction thanks to the air cushion technique. This consists of creating a thin cushion of air between 2 flat parts (track and glider) and raising the glider slightly, thereby eliminating friction.
- Page 4 Air track Take the air blower out of its packaging and connect the hose to the outlet in exactly the same way. Connect the power lead to blower. WARNING: Check that the variator switch is on the lowest setting. Start the blower. Place a glider on the track and increase the blower power until it moves without any friction.

3- Setup with electromagnetic launcher Replace the elastic launcher with the electromagnetic launcher. Connect the launcher to a 12V power supply. Place one of the springs at the front. Fit the launcher accessory on the glider. OPERATION: Place the launcher accessory against the launcher, compressing the spring. - Page 6 Air track 4- Setup with timer Fix the 2 photogate brackets onto the track using the nuts pre-mounted on the track. Unpack the timer and fit the 2 photogates onto the sensor brackets Put the photogate barrier rods on the gliders.
- Page 7 Experiments 1. Uniform rectilinear motion Launch the glider using the electromagnetic launcher and one of the springs in order to have a repeatable launch. Place the photogates x mm apart and measure the glider's travel time between the 2 photogates. Repeat the operation moving the 2 photogates further along the track (keeping the x mm gap between them).
- Page 8 Air track 2. Uniformly accelerated rectilinear motion Equip the track with the pulley holder (see §3.2) and the glider with the hook accessory (0.8g). Fasten the string to the glider and place a hooked weight (mass M) at the other end (passing the thread over the pulley). Release the glider using the launcher (without a spring).
- Page 9 3. Elastic interaction Place approximately the same weight on the 2 gliders, remembering that the first glider is equipped with the launcher accessory (16 g) and the second with the spring (0.7 g). Position the first glider on the launcher and the second stopped in the middle of the track.
- Page 10 Air track This demonstrates that the momentum is conserved: �� ⃗⃗⃗⃗⃗ = �� ⃗⃗⃗⃗⃗ + �� ⃗⃗⃗⃗⃗ In addition, as the kinetic energy is conserved: �� ∗ �� ∗ ��² �� ∗ �� ∗ �� ² = ∗ �� ∗ �� ²...
- Page 11 4. Inelastic interaction Set up the same configuration as before, but this time equip the two gliders with the hook and loop accessories (2 x 2 g). Position the first glider on the launcher and the second stopped in the middle of the track.

Air track 5. Inclined plane Using a lab stand, raised the end equipped with the launcher until the track is at an angle from horizontal. Release the glider using the launcher (without a spring). Place the photogates x mm apart and measure the glider's travel time between the 2 photogates.
