To Investigate friction of a variety of surfaces, find out the relation between weight and friction and Investigate ways to reduce friction using wheels and rollers. The set up can also be used to study Newton’s laws of motion, demonstrate the laws of motion using a Hall’s carriage and explore variable inertia. With Instruction manual.

To understand the relation between friction and smoothness of materials. Consists of three wooden blocks measuring approximately 3-15/16″ L x 2- 3/4″ W with hooks. The first block has a polished side, the second has a sandpaper side, and the third has an aluminum side. Complete with polished wooden base measuring 14″ L x 2-3/4″ W.

To demonstrate that shortest distance between two points is not necessarily the fastest while providing an excellent dramatization of potential and kinetic energy and friction. Two balls are released simultaneously one on a straight metal track, the other on a bent metal track.

To illustrate principles of lever and moment, five plywood beams 600 x 44 x 3 mm with ruled graduations at every 38 mm and a shallow groove across its centre for fulcrum point, with 4 wood fulcrums and forty 25 mm square metal blanks.

A one-meter-long rule, graduated in mm, numbered in cm and drilled every 2 cm. With a set of three riders & pins, one acts as fulcrum and the other two as mass hangers.

For investigating the nature of mass and the distinction between mass and weight. Two metal trays 130 x 55 x 23 mm are joined together with two spring steel strips of 23 mm width, the distance between the trays being 215 mm. One tray is drilled to accept 3 equal cylindrical masses. The other tray can be clamped to a bench horizontally or vertically. Complete with 3 masses and a ‘G’ clamp.
