WebAug 30, 2024 · Scalar Quantities are defined as the physical quantities that have magnitude or size only. For example, distance, speed, mass, density, etc. However, vector quantities are those physical quantities that have both magnitude and direction like displacement, velocity, acceleration, force, mass, etc. WebI pursued a master's in mathematics and ended up teaching the subject in a school. It was all going well until covid came in and things didn’t quite work out quite the way I wanted.
