Early zoning regulations were in some cases motivated by racism and classism, particularly with regard to those mandating single-family housing. [7] [8] Zoning ordinances did not allow African-Americans moving into or using residences that were occupied by majority whites due to the fact that their presence would decrease the value of home.

However, to distinguish acceleration relative to free fall from simple acceleration (rate of change of velocity), the unit g is often used. One g is the force per unit mass due to gravity at the Earth's surface and is the standard gravity (symbol: g n), defined as 9.806 65 metres per second squared, [5] or equivalently 9.806 65 newtons of force ...
All that was needed to obtain a numerical value for standard gravity was now to measure the gravitational strength at the International Bureau. This task was given to Gilbert Étienne Defforges of the Geographic Service of the French Army. The value he found, based on measurements taken in March and April 1888, was 9.80991(5) m⋅s −2. [6]
Units for other physical quantities are derived from this set as needed. In English Engineering Units, the pound-mass and the pound-force are distinct base units, and Newton's Second Law of Motion takes the form = where is the acceleration in ft/s 2 and g c = 32.174 lb·ft/(lbf·s 2).
In unit systems where force is a primary unit, like in imperial and US customary measurement systems, g c may or may not equal 1 depending on the units used, and value other than 1 may be required to obtain correct results. [2] For example, in the kinetic energy (KE) formula, if g c = 1 is used, then KE is expressed in foot-poundals; but if g c ...
Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity). The unit g (or g) represents multiples of the standard acceleration of gravity and is conventionally used.
Arizona voters will be able to decide in the Nov. 5 election if they support or reject a Republican-led measure that would make it a crime to cross the state border from Mexico and allow state ...
Various countries published standard values that should be used for g, and in 1901 the CGPM published a standard value for g that should be used in the "International Service of Weights and Measures", namely 32.174049 ft/s 2 (9.80665 m/s 2), which is equal to the value of g at 45° latitude. [55] Newton's second law in these systems becomes:
