| Humidity Ratio of Air |
| Humidity ratio W is the ratio of the mass of water vapor to the mass of dry air, Specific humidity γ is the ratio of the mass of water vapor to the total mass of the moist air sample: |

| Thin Double Convex Lens Optical Equations |
| Derivation formulas for lens essentially traces an arbitrary ray geometrically and mathematically from an object point through the two surfaces of a thin lens to the corresponding image point. |

| Refraction for Water at Various Temperatures |
| Table of index of refraction of liquid water at atmospheric pressure, relative to a vacuum, at several temperatures and wavelengths. It is generated from the formulation in Reference 1, which covers a wide range of temperature, pressure, and wavelength. |

| Thrown Javelin Flight Dynamics Physics Graphical Simulator |
| This model simulates the throw of a javelin with no spin and no wind in a vertical plane. This is a simplified situation to be able to analyze the pure dynamics of a javelin throw. The user can change several initial conditions including velocity, angle of the javelin (theta), angle of the velocity vector (phi), angle of attack (phi), and angular velocity (omega). |

| Roller Coaster Physics Graphical Simulator |
| This simulation simulates motion along a constrained path, such as what a roller coaster would take (assuming it has safety wheels to keep it on the track in “up-side-down” situations, of course). The simulation offers a chance to explore a number of concepts associated with roller coaster physics, including conservation of energy, reaction forces, motion in a vertical plane and friction. |

| Air Density Equation |
| Physical properties of air can be represented by the real gas equation, which is the modified version of ideal gas equation. |
