Linear Air Track - Extruded Aluminium, 2 Rows Of Holes, Graduated Scale | Dustproof, Waterproof, Wireless Light Gates With Timer

Linear Air Track with Accessories Precision provides a cost-effective system for exploring all aspects of dynamics involving linear motion in a virtually friction-free environment.It is an ideal teaching aid for physics.This Linear Air Track can be used to experimentally study in kinematics covering velocity, force and acceleration,momentum,potential energy, collisions (elastic /inelastic), conservation of energy,kinetic energy,simple harmonic motion,motion on level and inclined planes.It is particularly effective in the field of collisions where conservation of momentum is dramatically demonstrated. The Linear Air Track with a perforated rail has a smooth surface and high linearity and is made from strong extruded aluminium,lightweight yet durable.The rail has one row or two rows of fine holes on each side all along the length of the track.An inlet cover is given at one of the ends, which is connected to hose of an air blower. Compressed air is sprayed from the holes and forms a air cushion on the surface of the track. This air cushion fills the space between the air track and the inner surface of a glider. As a result, the gliders move on(float to and fro on) an air cushion can be regarded as almost friction-free. The Linear Air Track also has a scale graduated in millimeters for measuring distances and recording positions.Wireless light gates with built-in-timer provide accurate measurement of various kinematic parameters.It is supplied with a comprehensive accessories.An air source and a measurement are required to build a Linear Air Track System, which can be provided by our Air Blower and digital timer.
