Precisely crafted Physics Balls for all your Newtonian experiments. Great also for volume and density labs. All Steel balls are have chrome finish.
Assorted Physics Ball Set
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!
Drilled Physics Ball Set
These high quality 1" (25mm) drilled physics balls are great for doing Newtonian physics experiments such as collisions or for use in mass/volume experiments. A 3mm hole has been exactly drilled in the center of each sphere in such a way as to allow for the recessing of a knot. This allows the set to also be used as pendulums. These precisely crafted spheres come in pairs that are nearly identical which makes them ideal for comparing how different materials affect your experiment.
Set of 12 drilled balls contains 2 each of Steel, Brass, Aluminum, Lead, Cork and Wood. 1 balls come packaged 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.
Steel Balls
Steel balls with chrome finish are great for doing Newtonian physics experiments such as collision or for use in mass/volume experiments.
Steel Balls with Hole
Drilled balls are great to make pendulum bobs or for doing impact experiments. Steel balls have a 3mm hole drilled completely thru its axis with chrome finish.
1 inch Glass Ball
1" glass balls are great for doing Newtonian physics experiments or for use in mass/volume experiments.
1 inch Wooden Ball
How did physicist's conduct their experiments needing a steel sphere in the old days? They used wooden ones of course. Sanded smooth and 1" in diameter this wooden sphere can be combined with other spheres of various composition (steel ect..) to show how the rolling stopping distance varies with each material due to the difference in the coefficient of friction for that material. They also make a great relic for the grandkids when describing what physics "used to be like".
1 inch Styrofoam Ball
Styrofoam balls are great for doing mass/density experiments or use them as part of an experiment to compare the effects of how the different ratios of surface area to volume affects a falling object.
Styrofoam Balls 24/pk
Compare the effects of how a different ratio of surface area to volume affects a falling object with these styrofoam balls. 24 pack contains 6 each of 1" 1.5" 2" 2.5" in diameter balls.
