Apparatus to show the equality of acceleration under gravity between light and heavy objects in the absence of air resistance. Comprises a 100 cm acrylic tube with bungs at either end. A valve with a stopcock at one end allows a vacuum pump to be attached, and the air evacuated from the tube. Inside the tube is a coin, and a piece of paper (various laws prevent supply of a feather for this apparatus). When air is in the tube, the coin falls quickly but the paper is subject to air resistance and falls more slowly. With the air evacuated, the only force acting is gravity, so the two fall at equal rate, despite the difference in weight. The famous experiment on the Moon with hammer and feather can be seen here: http://timstar.co/HammerFeather

Self-contained apparatus for study of moments. Comprising high-quality aluminium stand, metre rule, three knife-edge sliders with hooks, two mass hangers, eight slotted masses 1-500 g, and storage rack. No additional apparatus such as retort stands required, and can be set up in 'moments'. Additional knife-edge sliders can be purchased if required. (FO180002)

Knife edge clamp for moment of force apparatus (FO180000). Ruler not included.

The balancing beam kit contains 5 sets of pre-drilled wooden beams with a central pivot and brass hooks to slot into the holes. The brass hooks are used to support slotted masses (not included) and the pivot is clamped into a retort boss head for support. Contents: 5 each of balance beams and pivots plus 10 brass hooks; enough for 5 groups or individual students.

This levers kit contains 5 sets of levers and accessories for students to investigate levers and moments. Each set includes a lever with precisely placed pre-drilled holes mounted on a plastic saddle, pivot rod and mounting base, along with 10 g mass carriers which slot into the lever holes. Each set requires a set of 10 g slotted masses (not included). Contents: 5 x lever kits.

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.

A blower specifically for the FO180610 air track.

A superb quality air track made from square section aluminium extrusion with supporting ""U"" channel. Linearity is +/- 0.03 mm. Suitable for elastic and inelastic collisions, momentum, speed and acceleration measurement. The track rests on three rubber feet, two of which can be adjusted. Each side has scale graduated in mm. The track is supplied with two carts and a standard accessory set. Additional accessories available on request. Dimensions (L): 2 metres. Standard Accessory Set contains: • Fork with plug connectors (3) • Holder with plate and plug connectors (3) • Holder with needle and plug connector (1) • Tube with wax and plug connector (1) • Holder with hook and plug connections (1) • 25 and 100 mm Apertures with plug connectors (1) • Weights 50 g for carts (4) • Pulley with connectors (1) and carts (2).
