it is for a physics project

Many different types are there. Involving electronic swithes or mechanical. Here is the description of a mechanical type:\n\n1. Take a flashlight that produces very bright light.\n2. Take a table/floor fan.\n3. Place the flashlight towards the fan's blades from behind the fan.\n4. Turn the fan ON.\n\nYou have strobe light. You can change the speed of the blinks by changing the speed of the fan.

Why not take a page from Archimedes' Eureka! moment?\n\nMeasure the density, then ask a jeweler.

Someone posted the exact same set of questions a few days back, either here or on the physics page - you ought to be able to find the methods in the responses. Have a look.\n\n\nBest of Luck - Mike

Hi. The experiment used a torsion scale, a very thin wire with known strength, to support the center bar. The smaller balls were attracted to the larger ones and caused the wire to twist just a little. From this the mass of the lead balls was used to calculate 'g'.

sure. go to a science store or look up schematics on the web.
