A g by Free Fall Apparatus To determine the value of ‘g’ by timing the fall of a steel ball. The release unit consists of a plate 90 x 45 x 3mm carrying a pair of metal clips connected to 4mm sockets. The clips are opened, thus dropping the ball and breaking the contact between the clips. The trip unit is mounted on a base measuring 100 x 100 x 12mm and comprises of a trip plate, the end of which bears upon the blade of a micro switch and holds it in the closed position. When deflected downwards by the impact of the ball the trip plate releases the blade and opens the switch. The trip plate comes complete with a protective rubber strip to prevent the switch from damage should it be accidentally struck directly by the ball. Kit comes complete with steel balls of 16mm and 19mm diameter. each £112.95

B Fast Timer The Fast Timer is a versatile, portable instrument for timing brief events with two ranges: 1 to 999.9ms and 1 to 9999µs. The inputs can be controlled by light gates, microphones or mechanical switches, connected via 4mm sockets. Two sockets provide 0 and 5V for connection to sensors if required. The usual care is needed when using microphones to ensure that a repeatable sharp edge is obtained, e.g. use a toffee hammer and steel slab to produce a sharp noise when measuring the speed of sound. Mass: 0.5kg. Size: 170 x 135 x 45mm. each £189.99
