Iranian Scientists Produce Air Track System for Physics Tests
“We are active in the field of building physics laboratory equipment, including the basic one and two topics, and we have gained more than 30 years of experience in this field,” said Ali Mohammad Khaleqi, the production manager of the company.
“The air track device is one of our products that is used in the field of basic two physics to analyze collisions and its relationship with physics formulas and it enjoys high accuracy and unique efficiency,” he added.
“Last year, we were able to sign a contract with Al-Zahra University to sell the air track system,” Khaleqi said.
An air track is a scientific device used to study motion in a low friction environment. Its name comes from its structure: air is pumped through a hollow track with fine holes all along the track that allows specially fitted air track cars to glide relatively friction-free. Air tracks are usually triangular in cross-section. Carts which have a triangular base and fit neatly on to the top of the track are used to study motion in low friction environments.
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.
