For determining the value of ‘g’ by measuring the time taken by a falling steel ball. The apparatus consists of a release unit and a trip unit. Both these units size 13x9x1cm are fitted with 4mm sockets and can be readily clamped on to a 12mm diameter rod. The release unit is fitted with a small solenoid type electromagnet which holds a steel ball. The solenoid helps in the prompt release of the ball on being disconnected. The trip unit has a swinging plate and is fitted with a switch. The switch is normally held closed by a magnet and is opened when the ball falls on the plate. The time of fall is measured by a digital Centisecond Timer. Supplied complete with steel balls but without Centisecond Timer, retort stand and base.

-01 Centisecond Timer for ‘g’ by free fall apparatus.

Comprising rods of different materials and some of different thickness to enable students to test for themselves different thermal conductivities. Kit comprises:
