Gravitational Balance

Gravitational Balance

Product Details:


Product Description


Principle and Working:

This instrument allows measuring G with a high precision (with a maximum error of 15%). In the initial displacement method,G is derived from the angular acceleration of the balance due to movement of the attracting masses from one side to the other. The equilibrium displacement method derives G from the change in the equilibrium position of the balance at rest due to the change in position of the large masses. The built-in oil damping system reduces the time needed for equilibrium.


  • Determining of G, the fundamental gravitational Constant.
  • Verifying the inverse-square law.
