It is used for kinematic and dynamic experiments in which for the purity of the experiment a system with a state where friction is reduced to zero is required.
The air track is a support with very little friction. Compressed air is pumped into the rail and exits through holes along the surface of the rail, forming a thin layer of air between the track and the bogies, making the bogies float. This allows you to create a closed system for the experiment and reduce to almost zero the influence of external influences. You can use these tools to test the laws of mechanics of conservation of momentum and force.
The air track is made of extruded aluminum tube with a triangular shape. The compressed air is fed from the blower to one end of the tube, then the air comes out of small holes along the track.
The exiting airflow forms a layer between the track and the cart, causing the cart to move on top of the track in a frictionless state.
This reduces the error caused by friction in the motion experiment, so the experimental data obtained can be considered close to the theoretical data obtained by calculation.
The cart moves along the track at a distance of 0.1 mm from the rail surface.
