Use in conjunction with an accurate millisecond timer to calculate acceleration due to gravity. The timer starts when the ball bearing is released from the release unit, the base has an integral vibration sensor which stops the clock as the ball bearing hits the impact plate. Replace the ball bearing, reset the timer and the unit is ready to go again.
This Charles Law Apparatus consists of a uniform capillary tube, 30cm long, sealed at one end and marked with a linear metric scale. The scale can be used to measure the height of an air column contained below a mercury bead.
The Lascells E-Field Detector provides a new and novel way to demonstrate charge. This highly sensitive electronic device is an essential piece of equipment in the Physics teachers’ armoury as it can detect very small charges and their polarity, as well as charge at a distance.
The Lascells Strobe Frequency Counter provides a compact, economic, reliable and simple way of detecting the frequency of a strobe light source. The sensor is calibrated to work with the Lascells ripple tank, allowing a quick measurement of strobe frequency.
