Introduction
Physics, the study of matter and energy, is a fundamental science that underpins much of our modern technology. From the smallest particles to the vastness of space, physics provides a framework for understanding the universe around us. Reference tables play a crucial role in physics, providing a quick and convenient way to access essential equations, constants, and other important information.
Reference Table of Key Equations
The following table summarizes some of the most commonly used equations in physics:
| Equation | Description |
|---|---|
| $F = ma$ | Newton’s second law of motion |
| $E = mc^2$ | Einstein’s mass-energy equivalence |
| $F_g = Gm_1m_2/r^2$ | Newton’s law of universal gravitation |
| $V = IR$ | Ohm’s law |
| $f = v/\lambda$ | Wave equation |
Reference Table of Physical Constants
Physical constants are quantities that have a fixed and unchanging value. The following table lists some of the most important physical constants:
| Constant | Value |
|---|---|
| Speed of light in a vacuum (c) | $299,792,458 \text{ m/s}$ |
| Gravitational constant (G) | $6.67408 \times 10^{-11} \text{ m}^3 \text{ kg}^{-1} \text{ s}^{-2}$ |
| Planck constant (h) | $6.62607 \times 10^{-34} \text{ J s}$ |
| Boltzmann constant (k) | $1.38065 \times 10^{-23} \text{ J K}^{-1}$ |
| Avogadro constant (N$_A$) | $6.02214 \times 10^{23} \text{ mol}^{-1}$ |
