Linear Air Tracks

This timer is most suited for an investigational approach for students to gain sound understanding of the concepts of time and motion. Two pairs of sockets alternately start and stop the timer, one pair operating in make mode, the other in break mode. The start/stop switches can be either mechanical or electronic. The timer is auto-ranging for ease of use and has clear 13mm digital display and has robust metal case with durable powder coat finish. An illuminated on/off switch is mounted on the rear panel adjacent to fused appliance inlet. • Electrical Supply: 220-240 V AC 50-60 Hz • Dimensions (W x L x H): 179 x190 x 85 mm • Mass: 1.6 kg • Ranges: 0 to 9.999s; 10 to 99.99s; 100 to 999.9s; 1000 to 9999s • Accuracy: ±0.01%

For use as a light operated timing gate. Comprises a photodetector and light source each housed in a robust ABS case spaced 40 mm apart on a plastic rod. Light source housing has a battery compartment and on/off switch. Photodetector housing is fitted with pair of 4 mm sockets to allow connection to electronic timers. When the timing gate is switched on it creates a short circuit between the two output sockets, this then becomes an open circuit each time the light beam is interrupted. Consequently the timing gate can be used as a remote switching device in wide range of dynamics experiments.

The air track measures 1.2 metres and is made from high strength 56 x 56 mm extruded aluminium. Includes instruction manual and accessory kit which enables investigation of: • Velocity • Force and acceleration • Potential energy • Kinetic energy • Conservation of energy • SHM • Motion on level and inclined planes

Air track blower suitable for use with the compact linear air track FO150710. Please note this blower is not powerful enough for larger air tracks.

A precision machined, metre linear air track, of lightweight yet durable aluminium extrusion construction. The length is drilled with holes, such that when attached to blower, near-frictionless surface is created. The track rests on three adjustable feet, so it can be made perfectly horizontal with respect to gravity. The kit includes set of accessories for wide range of investigations: • 2 sliders • 10 bolt and wing nuts • 4 spring attachments • 4 spring/string attachments • 4 springs • 2 Velcro attachments • 2 pulleys, strings • 4 slotted masses hanger • 8 photogate flags • 2 photogate arms • 1 latching cradle/bumper • 4 masses for the sliders • Assembly instructions experiment guide Air blower FO180615 sold separately.

Spare cart for the Frederiksen linear air track, TI68740.

Extremely quiet air blower with continuously adjustable speed for use with the premium air track TI68740. Complete with 1.7 metre hose. Mains supply: 220-240 V AC. Mass: 5.7 kg. Dimensions (L x W x H): 280 x 250 x 210 mm.

Comprising FO140110 Student Timer, and two TI170200 Photogates. Ideal for setups with air tracks, dynamics tracks, or other timing experiments which require light gates. Leads not included.

A double photogate with built-in timer and display, which is capable of precise speed measurements, in addition to all the usual tasks of single photogate. • Incorporates timer with display no separate timer required • Easy to operate • Double light barrier direct readout of speed • Laser optics give high precision measurements • Expandable with external sensors (e.g. microphones) • Use two SpeedGates for all the traditional collision experiments • Several SpeedGates can be daisy chained • Pendulum period mode prevents off-by-one errors • Auto rotating display Speedgate can be used as stand-alone unit or pair can be used to carry out all the experiments you can do with two traditional photogates and universal timer plus much more: with the precisely spaced double laser system you get speed readings without length measurements or calculations. The traditional passage time measurements are still possible, if preferred, for teaching purposes. The display divides into two parts giving you immediate access to all results. An adjacent status area shows when light rays are blocked, the state of external inputs etc. SpeedGate is battery powered so can be used as stand-alone unit no cables are required. However, the apparatus can also be powered via USB cable if preferred. It is operated using three pushbuttons, which control primary mode, secondary mode and reset. The reset button also functions as power switch. The primary and secondary modes each correspond to one part of the display. Suggested experiments: • Kinematics of uniformly accelerated motion • 'g' by freefall • Newton's second law • One-dimensional elastic and inelastic collisions • Mathematical pendulum • Speed of sound (requires 2 x SO150400 microphones) Two SpeedGates can be used for collision experiments; the double display will show the two latest measurements. Connect two (or more) SpeedGates together, using the Speedgate Cable, to measure the time interval between the gates e.g. for acceleration experiments. The whole chain is reset with one button press. The timer functions can even be used with external signals e.g. two microphones (SO86270) and SpeedGate makes complete setup for measuring the speed of sound. Easy to work with the display even orients itself automatically when rotated. The Bundle TI180110 comprises two Speedgate units a connecting cable.

This Photogate Unit is specially designed to be used together with the Electronic Counter or timer FO140110. It can be used as an optical switch, activated when the light beam is broken and for pendulum period measurements, air track timing, measuring period of rotation etc. The unit is made from impact-resistant plastic with threads for vertical and horizontal mounting using the supplied 10 mm diameter support post. The Photogate Unit is supplied with powerful red transmitter diode, in front of which is a 1 mm slit, and two LEDs on the sides of the unit (red for transmitter, green for receiver), indicating the function. The Photogate Unit can be connected directly to the DIN sockets of the counter and additional photocells can be daisy-chained and connected to the same counter input, for measurement of acceleration etc. Dimensions: 160 x 120 x 28 mm (W x H x D). Gap width: 90 mm.
