... / The electric field at the center of the square is the sum of the electric fields due to the four charges; and as is the case with Coulomb’s Law, the “tricky” part is to find the vector ~r for each. For example, ~r1 is the vector from q1 to the center, which can be gotten by moving a distance 21 a ...

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.
