Which are scalars?
Which are scalars? scalar, a physical quantity that is completely described by its magnitude; examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors. What do scalars mean? 1 : a real number rather than a vector. 2 : a quantity (such as mass or time) that has a magnitude describable by a real number and no direction. Who invented scalar? Lagrange (1736-1813) in 1777, followed by Laplace (1749-1827) in 1782, was the first to introduce the scalar gravitational potential. What is a...
