Inertial balance |

|
An inertial balance is a masser that responds, not to the weight of an object like a hanging spring, but to the mass (inertia) of an object. An inertial balance measures the same value on the ground, in an accelerating lift, and on the Moon. For instance:- 1 Oscillation balance The period of a mass oscillating on a light vertical hanging spring is 2p(m/k)0.5 where k is the spring constant and m is the inertial mass. The period is independent of the acceleration or the value of g. 2 Water balance
