Learn the basis of vectors and how to apply it to physics problems by comparing scalars and vectors, adding and subtracting vectors, components, coordinate systems, and unit vectors.
Explore the difference between scalars and vectors, including magnitude and direction. Learn how to write vector notation and distinguish displacement from distance and vector equality.
Apply graphical and arithmetic methods to add vectors, including parallel and non-parallel cases, derive the resultant, and learn about the commutative law, negatives, subtraction, and scalar multiplication.
Resolve a vector into its x and y components, ax and ay, using ax equals a cos theta and ay equals a sin theta, signs depend on quadrant.
Extract x and y components of a vector using cos and sin, with a 12 cm vector at 30 degrees, and determine magnitude from components 3 i plus 6 j.
Explore coordinate systems by defining the origin, axes, and labeling points, using Cartesian coordinates (x, y) and polar coordinates (r, theta) with examples.
Explore converting between polar and Cartesian coordinates, deriving x and y from r and theta, and vice versa using theta = arctan(y/x) and r = sqrt(x^2 + y^2).
Explore converting between Cartesian and polar coordinates by applying r = sqrt(x^2 + y^2), theta = arctan(y/x), and using x = r cos theta, y = r sin theta.
Understand unit vectors, dimensionless directions with magnitude one, denoted i, j, k, and express vectors as ax i + ay j + az k; add by components to get resultant.

Understanding vector basics: Learn the basic concepts of vectors, the difference between them and scalar quantities, and how to represent vectors graphically.
Learn how to add and subtract vectors and calculate dot and vector products to understand how they apply to physics problems
Understand how to apply vectors to analyze motion in different dimensions, including speed, acceleration, and forces acting on objects
Developing skills in solving physics problems that involve several forces or vectors in multiple directions
It aims to introduce students to the concept of coordinate systems, and enable them to understand how they are used to represent and determine locations on a 2D and 3D plane. Students will gain the ability to read and plot points in the Cartesian coordinate system, as well as convert between different systems such as polar and Cartesian. They will also learn the importance of coordinate systems in practical applications such as engineering drawing, navigation, and computer programming.
This lesson aims to enable students to understand the concept of unit vectors and their applications. Students will learn how to define a unit vector in 2D and 3D space, and how to use it to represent directions standardly. Students will gain the ability to calculate the unit vector for given vectors, and understand its applications in physics and engineering, such as representing force or velocity as vectors
This lesson aims to enable students to understand how to decompose vectors into their components in different dimensions. Students will learn how to divide a vector into its components along Cartesian axes (such as the X, Y, and Z axes), and how to use those components to represent vectors and simplify calculations. Students will also gain the ability to apply these concepts to scientific and engineering problems, such as force and motion analysis, enhancing their ability to solve vector problems effectively.
