This document defines scalar and vector quantities and provides examples of each. Scalars have only magnitude, while vectors have both magnitude and direction. Examples of scalars include mass, time, energy and distance, while vectors include displacement, velocity, acceleration and force. Vectors are represented by arrows with length indicating magnitude and direction. Properties of vectors are that they are equal if they have the same magnitude and direction, negatives have the opposite direction, and addition requires considering both magnitude and direction. The resultant vector results from adding vectors, while the equilibrant is opposite the resultant.

- 12. Two vectors are equal if they have the same magnitude and the same direction. A negative vector is a vector that has the opposite direction to the reference positive direction. When vectors are added, we need to take into account both their magnitudes and directions. The equilibrant is the vector which has the same magnitude but opposite direction to the resultant vector. 12
