aAn isosurface of a scalar or vector variable is typically a complex surface reflecting the distribution of the underlying variable. Isosurfaces of coordinates, however, are typically regular geometric shapes such as planes, cylinders, cones or spheres. 标量或传染媒介可变物的isosurface典型地是反射部下...

Examples of vectors in nature arevelocity, momentum, force,electromagnetic fieldsand weight. A quantity or phenomenon that exhibits magnitude only, with no specific direction, is called a scalar. Examples of scalars include speed, mass, electricalresistanceand hard drive storage capacity. What are vec...
Is angular momentum a scalar quantity? Angular momentum is avector quantitythat represents the product of a body's rotational inertia and rotational velocity about a particular axis. Is Area A scalar or vector? The area is ascalar quantityin geometry and mensuration. In physics, we associate dir...
1.(Mathematics)mathsAlso called:polar vectora variable quantity, such as force, that has magnitude and direction and can be resolved into components that are odd functions of the coordinates. It is represented in print by a bold italic symbol:For̄F. Comparepseudoscalar,pseudovector,scalar1,ten...

The density \(\rho \) may be replaced by any other thermodynamic real scalar or vector field, in which case \(\chi \) becomes a random matrix. It is shown in the sequel that the annealing limit of (21) requires at least the mathematics of quantum field theory to be described ...
Speed is considered a scalar because it only describes how fast something is going (just the magnitude), while velocity is a vector because it not only describes how fast an object is moving but also in what direction. It's often said that velocity is speed with a direction. Saying that ...

The evacuation speed of pedestrians through bottlenecks usually leads to the faster-is-slower (FIS) phenomenon, which relies on frictional clogging and clusters’ size. However, less attention is given in literature to the rheology of pedestrian crowds a
