A method for directly measuring the mass of an object comprising the steps of: a) exciting the object with a vibration by applying a non-constant but known force which changes as a function of time, said changing force being applied with a certain frequency; b) measuring the accelerations of the said object which are the results of the said non-constant force-application of step a) and obtaining a plurality of acceleration-measurements; and c) selecting from said plurality of acceleration-measurements the acceleration-component having the said certain frequency and deriving the mass of the said object. An apparatus for carrying out the said method. |
