Question

Can mass be measured in the absence of force (4 fundemental forces)? in complete isolation can a mass of an object be determined?

if yes how?

if not... then how can we define that the object even exists in absolute isolation ?

thank you

Answer 1

Mass can’t be measured in the absence of force (for gravitational interaction “mass” is mass, for electromagnetic – charge, and so on) Mass cant be determined in complete isolation is it is measure of interaction. ( Newton’s laws). We can determine that the object exist only if we can observe some interaction or change of state (the body begin to accelerate → some other massive body act on it).
