These lessons, with videos, examples and step-by-step solutions, help High School students recognize vector quantities as having both magnitude and direction. Represent vector quantities by directed line segments, and use appropriate symbols for vectors and their magnitudes (e.g.,v, |v|, ||v||,v).
Common Core: HSN-VM.A.1
In physics and mathematics, physical quantities are broadly categorized into two types: scalar quantities and vector quantities. The key difference lies in whether or not they possess a direction in addition to their magnitude (size).
The following diagram gives some examples of scalar and vector quantities. Scroll down the page for more examples and solutions on how to use scalar and vector quantities.
Scalar Quantities
A scalar is a quantity that has only magnitude (size or amount) but no direction. Scalars are described by a single number and a unit.
Vector Quantities
A vector is a quantity that has both magnitude and direction. Vectors are represented graphically as arrows, where the length of the arrow represents the magnitude, and the direction of the arrow represents the direction of the vector.
