Details

The Disk and Demonstration Race Set recreates a classic physics experiment and allows your students to observe real applications of abstract concepts. Rotational inertia is a measure of the resistance to a change in the state of rotational motion and is dependent on an objects mass and how that mass is distributed from the axis of rotation. This can be observed by racing combinations of the disks and ring down an incline. The object with the greater rotational inertia will always lose the race.

Set includes one metal ring: 3.5" diameter, 3oz; and two wooden disks: 5" diameter, 6oz & 3.5" diameter, 3oz

  • Race combinations of the 3 objects down an incline to demonstrate how rotational inertia is dependent on their mass and how that mass is distributed from the axis of rotation. The object with the greater rotational inertia will always lose the race
  • Both disks are made of sanded and varnished hardwood to minimize friction. The smaller disk and ring have identical masses and radii in order to have the same inertia but different rotational inertia. The 2nd disk has exacly twice the mass and a much larger radius
  • Ideal physics classroom aid to supplement physics studies of force and motion
  • Real application of abstract concepts
  • Set includes wooden disk, 5" diameter, 6oz (1); wooden disk, 3.5" diameter, 3oz (1); metal ring, 3.5" diameter, 3oz (1)

What Educators are Saying About Geyer

Justin has been nothing but helpful and professional in my requests for these Boeing Defense requirements. He has been able to answer my questions and concerns quickly, and helped in securing the order that I may have made with another supplier had be not been the value-add that he is to your company. I hope his merit raise this FY was "exceeds expectations".

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
