    A vector quantity has both magnitude and direction. Acceleration, velocity, force and displacement are all examples of vector quantities. A scalar quantity has magnitude, so the direction is not important, (examples include speed, time and distance). A scalar can also have sign (such as work done and charge).
    Electric Current (Scalar Quantity) (I) Electric current I = q/t. As both charge and time are scalars, therefore electric current is a scalar quantity. (II) We show electric current in a wire by an arrow to indicate the direction of flow of positive charge.

    A scalar quantity is a quantity that can be measured by one number. This is in contrast to a vector quantity, that has to be represented by two, or more, numbers. Rtc orlando 1982
    Jul 19, 2020 · A zero rank tensor is a scalar, a first rank tensor is a vector; a one-dimensional array of numbers. A second rank tensor looks like a typical square matrix. Stress, strain, thermal conductivity, magnetic susceptibility and electrical permittivity are all second rank tensors.
  • Conversion from mass to weight. Newton's second law is used to convert between weight (force) and mass: . The equation for force is F = ma (force = mass × acceleration).. Here, F is the force due to gravity (i.e. the weight), m is the mass of the object in question, and a is the acceleration due to gravity, on Earth approximately 9.8 m/s² or 32.2 ft/s²).

    A scalar is specified by mere number and unit, where the number represents its magnitude. A scalar may be positive or negative and they have no direction. The physical quantities which have both magnitude and direction are called vector quantities or vectors. Examples:Displacement, velocity, momentum, force, acceleration, torque etc.Tableau server installation
    Whereas a Vector quantity is the one which is specified by its magnitude as well as its direction that is associated with it. Some of the vector quantity are velocity, acceleration, displacement and angular velocity. Therefore, Scalar: Volume, Mass, Speed, Velocity, Density, Number of Moles, Angular Frequency

Jul 17, 2015 · The scalar product between two vectors yields a scalar quantity. Geometrically, this quantity is equal to the product of the magnitude of one vector’s projection on the other and the magnitude of the “other” vector: Using the components of vectors along the Cartesian plane, we could obtain the scalar product as follows. If the vector and ...
