Inertia Balance Kit (P-1570)
It is a class room demonstration kit for qualitative investigation of nature of mass and making students understand distinction between mass and weight. Kit comprises two metal trays 130 x 50 mm held 200 mm apart approximately on spring steel strips attached to the sides. One tray has holes to take three equal mass cylinders approximately (L x D) 100 x 25 mm each. The other tray acts as anchor and may be clamped to the bench either horizontally or vertically. Three support pins are supplied to fit radial holes in cylinders. Supplied complete with G clamp for mounting.

'g' By Free Fall Apparatus (P-1620)
This apparatus is used to determine G by measuring the time of fall of a steel ball through a pre-determined distance. The time taken being less than one second, a centi second/ milli second timer capable of measuring the time in fraction of seconds has to be used. Comprises two units each of which is mounted on a plastic which can be clamped on a 12 mm diameter retort rod. Connections are taken out to 4 mm sockets. The solenoid unit has a metal core which facilitates prompt release of the sphere on de-energizing. The gate switch comprises a hinged steel plate to hold against an adjustable contact by means of a small permanent magnet, the plate falls away promptly at the impact of falling steel ball. The apparatus is supplied with a solenoid unit, gate switch, Steel Ball 18 mm dia and a stand. Accuracy : Centi second timer P-1285
