The determination of the gravitational constant ‘g’ is one of the most fundamental and early physical constants students must derive and observe. This kit has a wooden base, 1.1m rod and a movable electromagnet. The electromagnet can be moved anywhere on the rod and is powered by the timer. When the ball is released, the timer is triggered and stopped once the ball has landed on the base for a precise measurement and then calculation of ‘g’. Supplied with manual.

Consists of one support, 5 plumb lines, 1 roll of tape, and 5 figures (triangle, L, trapezoid, parallelogram, parallelopiped). This kit helps students in the individual research of the center of gravity of a flat body, the conservation of the result on paper, the possibility of a graphic verification, and the discovery of the geometric research method.

Demonstrate the effect of pressure to water depth.

Mounted on molded plastic base, the unit consists of a base into the top of which may be screwed one of a set of four vases of differing shapes. An aperture in the bottom has a thin rubber diaphragm across it, bearing upon the short arm of the lever pointer. A moveable index on the vertical rod enables the height of water in vases to be set at same level. The apparatus is mounted on moulded plastic base that measures 25 x 17.5cm. The experiment is performed by screwing in each vase, in turn, and filling with water to the same level. It will be seen that the given height of water will result in the same deflection of pointer whatever shape of the vase.
