Is the mass of a particle taken as an exact number by empirical experimentation?

In this question the first comment says that it would be easy to test for variation in mass of particles, but none has been seen; so I wonder: Is the mass of a particle an exact number by experience? Or is it a consequence of some theory in…

Why does the center of mass of a system not change if there is no external force?

In the book "AP Physics 1 Essentials" by Dan Fullerton, question 6.32 entails a raft/boy system: A 30kg raft with dimensions 3m X 3m that is motionless on a lake.A 40kg boy crosses from one corner of the raft to the other. Neglect friction. Part A…

Why is it that fretting a guitar chord at the first few frets results in an out of tune chord assuming it was in tune in the open position

My theory why open chords do not play in tune when fretted on a guitar is that in the case of the first three strings, (the smallest ones), the strings being a different diameter from each other, will stretch at a different rate from each other due…
