Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Magnitude and direction together.
A vector is a mathematical quantity that has both magnitude (size) and direction. This distinguishes it from a scalar, which has only magnitude. For example, velocity is a vector (e.g., 60 km/h north), while speed is a scalar (e.g., 60 km/h).
↳ Vectors always include both size and direction; scalars have only size.
How we write vectors.
Vectors are often written in bold (e.g., v) or with an arrow above the letter (e.g., $\vec{v}$). In print, bold is common; in handwriting, the arrow is used. The magnitude of vector v is written as $|\vec{v}|$ or simply $v$.
↳ Vectors are denoted by bold or arrow notation; magnitude uses absolute value bars.
Vectors are everywhere in physics.
↳ Displacement, velocity, acceleration, and force are all vector quantities.
Vectors are fundamental quantities in physics that have both magnitude and direction, distinguishing them from scalars. They can be represented graphically, in component form, and added using tip-to-tail or algebraic met...

18 questions laddered from warm-up to topper-level, each with an explanation. A taste:
What is the solution to the equation $2x + 3 = 11$?
Beginner$x = 4$
Subtract 3 from both sides: $2x = 8$, then divide by 2: $x = 4$.
Which of the following is a linear equation in one variable?
Beginner$3x - 7 = 2$
A linear equation in one variable has the form $ax + b = c$ with $a \neq 0$; $3x - 7 = 2$ fits.
Solve: $5 - 2x = 3x + 10$
Intermediate$x = -1$
Add $2x$ to both sides: $5 = 5x + 10$, subtract 10: $-5 = 5x$, divide by 5: $x = -1$.
What is the slope of the line $y = -3x + 2$?
Beginner$-3$
In slope-intercept form $y = mx + b$, $m$ is the slope. Here $m = -3$.
