The Cavendish Gravitational Balance is part of the advanced physics products offered by Spectrum Scientifics. Built by United Scientific, these advanced physics devices are built on demand and are excellent for University or Advanced High School physics classes.
The Cavendish Gravitational Balance is used to help students and teachers measure the Universal Gravitational Constant, also known as “‘G”. “G” as some of you may remember is rather small since gravity is a very weak force. The exact measurement is 6.67384 × 10-11 m3 kg-1 s-2. This has been accurately determined by a couple of centuries of experimentation and math. The Cavendish Gravitational Balance will allow students to measure ‘G’ to within 15% accuracy.
