empirical constants

Empirical constants are values derived from experimental measurements or observations that reflect fundamental properties of nature. They are not derived from theoretical predictions but are established through repeated experiments. For example, the acceleration due to gravity on Earth (approximately 9.81 m/s²) is an empirical constant, as it is determined by measuring how fast objects fall. These constants play a crucial role in physics and engineering, helping scientists and engineers create accurate models and predictions about the behavior of physical systems. They are essential for ensuring consistency and reliability in scientific work.
