An air track is a perforated rail which is connected to an air blower. Compressed air is sprayed from the holes and forms a thin layer on the surface of the track. This layer fills the space between the air track and the inner surface of a glider.

Why is an air track used in physics?
The air track is also used to study collisions, both elastic and inelastic. Since there is very little energy lost through friction it is easy to demonstrate how momentum is conserved before and after a collision. The track can be used to calculate the force of gravity when placed at an angle.
How does an air track work?
The airtrack consists of a long metal tube with holes along its length. Air is blown from a pump into the tube. The air which escapes through the holes provides a near friction free cushion which gliders can ride on.
How does an air track reduce friction?
Compressed air is injected into the cavity beneath the track. Since this cavity is sealed, the air can only escape through the small holes on the track itself. This provides a force strong enough to lift the gliders, which drastically lowers friction.
Do air tracks remove friction?
Ideally, the air track eliminates friction by supporting the carts with air. However, the carts are still exposed to drag, as well as some friction with the track because the air flow out of the holes is not uniform.
What are air tracks made of?
Airgym AirTracks are built with Double Wall Fabrics. This material should be seen as 2 layers that are coated and held together by thousands of fibers. The Double Wall Fabric construction is extremely strong and functional. A typical cosmetic nature of this material are the slight dents who tend to disappear over time.
What is the aim of linear air track experiment?
INTRODUCTIONThe aim of this experiment is to determine the flatness of a linear air track ,using a gliderthat has a flag attached/ inserted on to it. This flag is what is going to be sensed by the4 photogates placed on the linear air track these photogates are placed at 30 cm intervals.
Why is a bowling ball better for knocking down pins than a ping pong ball?
1. Why is a bowling ball better for knocking down pins than a ping pong ball? A bowling ball is much more massive than a ping pong ball.
How do you level air track?
How do you set up an air track?
What might excessive air pressure cause the glider to do on the track?
Excessive air pressure may cause the glider to wander on the track, even in the absence of an accelerating force. The Air Supply will slightly heat the Air Track, causing it to expand.
What is velocity of separation?
Velocity of approach or separation is defined as the rate of change of relative displacement between two bodies (i.e. how fast a body approaches another body).
What are Photogates?
Photogates are a timing device that measure times of the changes in state of an infrared beam that is blocked by a flag of known length, as well as the times the beam is unblocked. Using the flag length, and the blocked time, students can calculate speed.
How is the speed of the glider measured in the experiment?
6. Calculating the speed of a glider in an experiment. Now that you know the effective length of the flag, you can calculate the average speed of the glider as it moves through the photogate by dividing the effective length of the flag, Leff, by the time the flag keeps the timer activated, ∆t.
Can air tracks float?
Yes, of course you can. Our mats are made with high quality materials that allow the mats to successfully float. Plus they can be inflated within 3 minutes with the manual air pump or 30 seconds with the electric air pump.
Are air tracks bouncy?
Air tracks provide great bounce-back that can improve height. Air tracks allow gymnasts to practice moves, again and again, to build their confidence and learn new skills.
Can an air track get wet?
Yes, Yes, Yes. Fbsport air products (airtracks) are waterproof. You are free to have fun with them in the water, or in the snow. Fbsport airtracks are made from durable Double-Wall Material, which is 10mm-thick commercial grade PVC tarpaulin.
How do you find approach velocity?
In one dimension, if bodies A and B are travelling at velocities →vA and →vB the velocity of approach can be said to be either →vA−→vB or →vB−→vA. Taking the magnitude of the subtraction does not work as one could envisage a negative velocity of approach where the bodies are moving away from one another.
What happens to the kinetic energy of a system during a collision?
Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. If total kinetic energy is not conserved, then the collision is referred to as an inelastic collision.
How does an object’s momentum change when it collides with another object?
During a collision, an object always encounters an impulse and a change in momentum. During a collision, the impulse which an object experiences is equal to its velocity change. The velocity change of two respective objects involved in a collision will always be equal.
Why is it important to level the track?
An accurate levelling of the track is important and consequently its faults affect the rolling stock and cause dynamic overloads on the rails, therefore checks of this and other track parameters are necessary (alignment, width, etc.)
How thick should an AirTrack be?
Air track mats are thick enough to withstand great force, with mats usually 10-20cm thick. A thicker mat provides a safe landing for gymnastic and aerobic exercises.
Do air tracks pop easily?
Do air tracks pop easily? No, it’s very rare for an air track to pop. If using the air track outside you must avoid leaving sharp objects like twigs and stones underneath. Contact with a sharp object could cause a puncture so some people place a tarpaulin on the ground first to give extra protection outside.
How wide should an AirTrack be?
A standard AirTrack is 2 meters wide. The P3 however, is also available in 2.8 meters in width. On this track, two lanes can be used simultaneously, making it a great choice for larger groups or when a high through-put is required. The diagonal of a standard competition floor is 16.97 meters.
How long do air tracks last?
This of course depends on the use of the airtrack. But with normal use and good maintenance, the airtrack will last about 5 years.
