Vector quantities are described numerically using both magnitude (size) and direction. This is typically done by providing the magnitude of the vector followed by an angle representing its direction, or by breaking the vector into its components along the x, y, and z axes. Another method involves using unit vectors to represent direction and scaling them by the magnitude of the vector.
The resultant of two vector quantities is a single vector that represents the combined effect of the individual vectors. It is found by adding the two vectors together using vector addition, taking into account both the magnitude and direction of each vector.
Scalar quantities are easier to deal with, the math is simpler. But if you have quantities that include both a magnitude and a direction, you really have no choice but using a vector quantity, to represent them correctly.
No, scalar can be added together directly, whereas vectors can only add their separate components together.
Scalar quantities are physical quantities that are described by their magnitude only, with no direction, such as temperature or speed. Vector quantities are physical quantities that are described by both magnitude and direction, such as velocity or force. An example of how they are alike is that both scalar and vector quantities can be added or subtracted using mathematical operations. An example of how they are different is that vector quantities have direction associated with them, while scalar quantities do not.

what graph uses symbols to represent amounts
Mainly because they aren't scalar quantities. A vector in the plane has two components, an x-component and a y-component. If you have the x and y components for each vector, you can add them separately. This is very similar to the addition of scalar quantities; what you can't add directly, of course, is their lengths. Similarly, a vector in space has three components; you can add each of the components separately.
Vector quantities can be added and subtracted using vector addition, but they cannot be divided like scalar quantities. However, vectors can be multiplied in two ways: by scalar multiplication, where a scalar quantity is multiplied by the vector to change its magnitude, or by vector multiplication, which includes dot product and cross product operations that result in a scalar or vector output.
A graph can represent relationships between quantities without using numbers by employing visual elements such as shapes, colors, or sizes. For instance, different shapes can symbolize various categories, while the proximity of these shapes can indicate the strength of their relationships. Additionally, the use of arrows can illustrate direction or flow, while varying colors can represent different attributes or states. This way, viewers can interpret the relationships qualitatively based on visual cues rather than numerical data.
Vector quantities are important in our daily lives because they describe quantities that have both magnitude and direction. For example, velocity is a vector quantity that describes how fast an object is moving and in what direction. This is essential in activities such as driving a car, navigating using GPS, or playing sports like basketball where direction matters along with speed.
