A Must Have Item for Physics Laboratories!
These high quality assorted physics balls are great for doing Newtonian physics experiments such as collisions and pendulums or for use in mass/volume experiments. This set contains every type of sphere that you could need all conveniently packed in a nice plastic case that includes a foam bottom which holds each ball securely in place to insure that this set will stay in great condition.
For starters you will find 1 each of the popular 1" (25mm) drilled balls made of steel, copper, lead, aluminum, brass and wood which have a 3mm hole exactly drilled in the center so that a knot can be recessed. Next add the always handy 1" (25mm) solid steel ball and a second 1" (25mm) solid steel ball that has bifilar suspension lugs. Not to forget the hooked spheres, this set contains 1 each of brass, lead and steel in a 1.5" (38mm) hooked version. Lastly we have added a 1.5" (38mm) solid cork ball.
This set is a terrific value. You get everything that you can do with a density block set combined with the much greater versatility of a quality sphere set all in one!
