ABSTRACT:
The present paper is based upon the
fact that if an object is part of a highly stable oscillating system, it is
possible to obtain an extremely precise measure for its mass in terms of the
energy trapped in the system, rather than through a ratio between force and
acceleration, provided such trapped energy can be properly measured. The subject
is timely since there is great interest in Metrology on the establishment of a
new electronic standard for the kilogram. Our contribution to such effort
includes both the proposal of an alternative definition for mass, as well as
the description of a realistic experimental system in which this new definition
might actually be applied. The setup consists of an oscillating type-II
superconducting loop subjected to the gravity and magnetic fields. The system
is shown to be able to reach a dynamic equilibrium by trapping energy up to the
point it levitates against the surrounding magnetic and gravitational fields,
behaving as an extremely high-Q spring-load system. The proposed energy-mass equation applied to the electromechanical
oscillating system eventually produces a new experimental relation between mass
and the Planck constant.
