  2. Scalar (physics) - Wikipedia

    en.wikipedia.org/wiki/Scalar_(physics)

    A scalar in physics and other areas of science is also a scalar in mathematics, as an element of a mathematical field used to define a vector space.For example, the magnitude (or length) of an electric field vector is calculated as the square root of its absolute square (the inner product of the electric field with itself); so, the inner product's result is an element of the mathematical field ...

  3. Force - Wikipedia

    en.wikipedia.org/wiki/Force

    The concept of force makes the everyday notion of pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity. The SI unit of force is the newton (N), and force is often represented by the symbol F. Force plays an important role in classical mechanics.

  4. Work (physics) - Wikipedia

    en.wikipedia.org/wiki/Work_(physics)

    This component of force can be described by the scalar quantity called scalar tangential component (F cos(θ), where θ is the angle between the force and the velocity). And then the most general definition of work can be formulated as follows: Area under the curve gives work done by F(x).

  5. List of physical quantities - Wikipedia

    en.wikipedia.org/wiki/List_of_physical_quantities

    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), and whether the quantity is conserved.

  6. Pressure - Wikipedia

    en.wikipedia.org/wiki/Pressure

    Pressure is a scalar quantity. It relates the vector area element (a vector normal to the surface) with the normal force acting on it. The pressure is the scalar proportionality constant that relates these two normal vectors: = =.

  7. Euclidean vector - Wikipedia

    en.wikipedia.org/wiki/Euclidean_vector

    Another quantity represented by a vector is force, since it has a magnitude and direction and follows the rules of vector addition. [7] Vectors also describe many other physical quantities, such as linear displacement, displacement , linear acceleration, angular acceleration , linear momentum , and angular momentum .

  8. Flux - Wikipedia

    en.wikipedia.org/wiki/Flux

    For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface. [1]

  9. Scalar field - Wikipedia

    en.wikipedia.org/wiki/Scalar_field

    The force is a vector field, which can be obtained as a factor of the gradient of the potential energy scalar field. Examples include: Examples include: Potential fields, such as the Newtonian gravitational potential , or the electric potential in electrostatics , are scalar fields which describe the more familiar forces.
