... It's my goal in this paper to pass on what I've learned in a way that nearly everyone can understand. I've left out nearly all the mathematics and electric circuitry involved. It was hard to do. Professor Spears math is quite elegant and to the point. Of all the physics concepts I've studied involvi ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
