BigG

constexpr auto playrho::BigG = Real{6.67408e-11f} * CubicMeter / (Kilogram * SquareSecond)

constexpr

Big "G".

Gravitational constant used in calculating the attractive force on a mass to another mass at a given distance due to gravity.

EarthlyLinearAcceleration

constexpr auto playrho::EarthlyLinearAcceleration = Real{-9.8f} * MeterPerSquareSecond

constexpr

Earthly gravity.

An approximation of the average acceleration of Earthly objects towards the Earth due to the Earth's gravity.

Note

This constant is only appropriate for use for objects of low mass and close distance relative to the Earth.
