WebApr 9, 2024 · Physical quantities can be classified into two categories, which are scalars and vectors. Quantities like mass or density can be described by their numerical values and appropriate units only. These quantities are called “scalars”. However, quantities like velocity or force require the specifications of a numerical value and a direction. WebVector quantity is used to examine the kinematics and mechanics using the analytical or geometrical method. Motion in two- and three-dimensional space is easily studied by their vector notation. Displacement, velocity, force, acceleration, momentum, torque, and weight are vector quantities. A scalar quantity is used in one-dimensional motion. commandfile.run is not a function
