A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. Main examples of scalar quantities are speed, time, etc. It’s the energy transferred to or from an object via the application of force along a displacement (s). It has a magnitude but no direction associated with it. 0 ⋮ Vote. The physical quantities are of generally two types namely vector quantity and scalar quantity. So kinetic energy does not depend on direction, hence it must be a scalar, not a vector. Vector Quantities: Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction. Work is a scalar quantity. Is work a scalar or vector quantity? The dot product always gives a scalar quantity. A vector is often written in bold, like a or b so we know it is not a scalar: so c is a vector, it has magnitude and direction but c is a scalar, like 3 or 12.4 Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction. Services, Working Scholars® Bringing Tuition-Free College to the Community. If a force acts on a body and the body undergoes a displacement, the amount of work done is the product of force and displacement parallel to the force. On the contrary, the dot product of vector quantity is always scalar. The scalars are those quantities that have only magnitudes.
