Describe Can you find two vectors with different lengths that have a vector sum of zero?
A vector quantity is defined as the physical quantity that has both directions as well as magnitude. A vector with the value of magnitude equal to one and direction is called unit vector represented by a lowercase alphabet with a “hat” circumflex. That is . Vectors have both magnitude and direction, one cannot simply add two vectors to obtain their sum. The addition of vectors is not as straightforward as the addition of scalars. To better understand this, let us consider an example of a car travelling 10 miles North and 10 miles South. Here, the total distance travelled is 20 miles but the displacement is zero. The North and South displacements are each vector quantities, and the opposite directions cause the individual displacements to cancel each other out.
