The table usually lists only one name and symbol that is most commonly used. The final column lists some special properties that some of the quantities have, such as their scaling behavior (i.e. whether the quantity is intensive or extensive ), their transformation properties (i.e. whether the quantity is a scalar , vector , matrix or tensor ...
Jerk (physics) Jerk (also known as jolt) is the rate of change of an object's acceleration over time. It is a vector quantity (having both magnitude and direction). Jerk is most commonly denoted by the symbol j and expressed in m/s 3 ( SI units) or standard gravities per second ( g0 /s).
A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation .
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. [1] : 445 Gauge pressure (also spelled gage pressure) [a] is the pressure relative to the ambient pressure. Various units are used to express pressure.
In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [ 1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones ). Most high- and low-pressure areas seen on weather maps (such as surface weather ...
Dynamic pressure. In fluid dynamics, dynamic pressure (denoted by q or Q and sometimes called velocity pressure) is the quantity defined by: [1] where (in SI units): u is the flow speed in m/s. It can be thought of as the fluid's kinetic energy per unit volume . For incompressible flow, the dynamic pressure of a fluid is the difference between ...
