Vectors and scalars. • mathematical quantities used to describe the motion of objects. • a vector has both magnitude and direction and. may be described using letters, coordinates. matrices or arrows. • a scalar has magnitude only described by. a single real number representing. a measurement, e.g. length. examples:. Scalars and vectors sample space scale, scale factor scalene triangle scatter diagram, scatter plot scientific notation score seasons secant, sec second secondary data set section, cross section sector sector graph segment of a circle segment of a line semicircle semiprime senary septagon septenary sequences sequence rules series set seven.

In mathematics and physics, a scalar is a quantity that only has magnitude (size), while a vector has both magnitude and direction. examples of scalar quantities include pure numbers, mass, speed, temperature, energy, volume, and time. examples of vector quantities include velocity, acceleration, momentum, displacement, and forces, such as. A scalar is a number, like 3, 5, 0.368, etc, a vector is a list of numbers (can be in a row or column), a matrix is an array of numbers (one or more rows, one or more columns). in fact a vector is also a matrix! because a matrix can have just one row or one column. so the rules that work for matrices also work for vectors. A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. you can tell if a quantity is a vector by whether or not it has a direction associated with it. example: speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude. the speed is the magnitude of the velocity. Video transcript. in this video, we will learn how to define physical quantities as scalars or vectors, depending on whether they have a direction. let’s begin by thinking about what a physical quantity is. a physical quantity is something that can be measured. examples of physical quantities include mass, length, force, and so on.

Vectors and scalars. scalars have a size, while vectors have both size and direction. when adding vector quantities, it is possible to find the size and direction of the resultant vector by. 1. engage students with interactive models. the conceptual and abstract topics, like scalar and vectors, need powerful visuals for a proper explanation. so, traditional lecturing methods fall short in this regard. interactive models are a powerful tool for teaching complex concepts like scalars and vectors.
