# What is the function of the airtrack in this lab?

An air track is an experimental apparatus that allows the study of motion with minimal interference by frictional forces. It consist of a track with many small holes through which air is blown continuously.

## What is an air track in physics?

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.

## 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 is an air track made of?

What are air tracks made of? At All About Gymnastics, our air tracks are made of high-grade PVC providing a soft, non-slip, durable surface that’s easy to clean. The body of the Air Track is reinforced 0.2mm drop stitch double wall fabric (DWF), brush finished.

## 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.

## 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.

## How will you measure the velocity of the gliders?

Using the scale along the length of the Air Track, measure the distance between the centres of the two gates. Divide this distance in millimetres by the time taken in seconds and calculate the average velocity of the glider between the two gates in mm/sec.

## 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 do you find the acceleration of a glider?

Recall, the theoretical acceleration of the glider is equal to the acceleration due to gravity g multiplied by the ratio of the mass of the falling weight and the mass of the weight and glider together. As the theoretical values on this table show, acceleration decreases as the mass of the glider increases.

## What is the velocity of glider 1?

Glider 1 has a mass of 2.0 kg and a velocity of 2.6 m/s.

## 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.

## Where are Air tracks made?

Since then the airtrack passed through several phases beginning with the wavy floor with a rope structure and ending with the German Double Wall Fabric that we currently use. Our products are 100 % manufactured in our own factory in Europe.

## Are air tracks good?

Air tracks are definitely worth it if you want to spend extra time working on tumbling skills outside the gym. Even the cheaper versions found on Amazon are usually of decent quality and have good value for money however I would recommend using one of the more established brands if your budget allows it.

## Is an AirTrack bounce?

AirTrack is like a bouncy floor and you can use it for gymnastics, cheerleading, parkour, tricking and in all kind of jumps and flips. With AirTrack you can securely train jumps and flips without fear of landing too hard. AirTrack provides bounce, which gives more air and power to your jumps.

## 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.

## Why must an an air track be level?

To study motion with constant velocity it will be necessary to level the air-track as carefully as possible so that the rider does not tend to accelerate in one direction.

## What happens to the kinetic energy of a system during a collision?

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.

## What will happen to acceleration of mass spring system if its mass is doubled?

Thus acceleration of body becomes halved if the mass of the body is doubled when same force is applied.

## How do you find momentum physics?

Momentum Equation for these Calculations: The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v).

## Is the velocity of an object increases then its kinetic energy?

Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples.

## What rule governs the velocities of two colliding objects?

Collisions are governed by Newton’s laws. The law of action-reaction (Newton’s third law) explains the nature of the forces between the two interacting objects.
