There is a big difference between Scalar and vector quantity. Vector quantity means something where direction is not important.eg- Displacement(the shortest distance between the displacement points of an object). whereas in scalar quantity Direction is important. eg. Speed
Studying vector and scalar quantities is important in physics because it helps us understand the physical world in a more precise manner. Vectors have both magnitude and direction, which is crucial for describing motion and forces accurately. Scalars only have magnitude and are useful for describing quantities like speed and temperature. Understanding both types of quantities enhances our ability to analyze and solve physics problems.
The gradient dot product is a key concept in vector calculus. It involves taking the dot product of the gradient operator with a vector field. This operation helps in understanding the rate of change of a scalar field in a given direction. In vector calculus, the gradient dot product is used to calculate directional derivatives and study the behavior of vector fields in three-dimensional space.
Velocity differs from speed in that velocity includes the direction of movement in addition to the magnitude of speed. Therefore, velocity is a vector quantity that specifies both speed and direction, while speed is a scalar quantity that only represents the magnitude of motion.
The term vector can be used in a variety of ways in science. In epidemiology, the study of disease spread, a vector is an organism that carries the disease from one host to another. So, for example, a mosquito is the vector of the organism that causes malaria. The vector may or may not be affected by the disease causing organism, but the point is that it is a third player in the interaction that includes host, parasite, and vector. Another definition of vector is the representation of a quantity that has magnitude and direction, and can be depicted by an arrow with a certain length (magnitude) and angle (direction). This can be helpful in science when one wants to sum or multiply quantities that have magnitude and direction, and there are rules for doing this that can be found in the field of "vector calculus" or "vector algebra". For example, in the Lotka-Volterra model of predator-prey dynamics, one can deduce outcomes of interactions by using vector algebra, and can determine if the predator and prey can coexist stably or not.
A study that coolects data
Measures of motion (displacement, velocity, acceleration) and forces are all vectors so any study involving these would require vector calculus.
Price and quantity demanded are both interdependent: there is not an independent variable. From that point of view, there is no reason to put one variable on the x-axis rather than the other.However, putting price on the horizontal axis makes it simpler to add the supply curve on the same chart, and then study the market equilibrium.Price and quantity demanded are both interdependent: there is not an independent variable.

Mechanical engineering usually deals with forces and their effects on materials. Forces are vectors and so, to study their effects you need to use vector calculus.

Some different terms are used for mathematics, but the general terminology for the broad-based subject are: Arithmetic (study of quantity), Algebra (study of structure), Geometry (study of space), and Analysis (study of change).
To study the concepts of quantity and change in their most abstract forms.
