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 alone is not enough.
In physics, quantities are either scalars or vectors. A scalar has only magnitude (size), like temperature or mass. A vector has both magnitude and direction, like velocity or force. This distinction is crucial because many physical laws require direction to make accurate predictions.
↳ Vectors include direction; scalars do not.
Arrow with purpose.
A vector is a mathematical object with magnitude (length) and direction (angle). It is often represented as an arrow: the length shows magnitude, the arrowhead shows direction. Common notations include $\vec{v}$ or $\mathbf{v}$.
↳ A vector has both size and direction, shown as an arrow.
Breaking vectors into parts.
A vector can be split into components along perpendicular axes (usually x and y). For a vector $\vec{v}$ with magnitude $v$ and angle $\theta$ from the x-axis:
↳ Components make vector math easier.
Vectors are fundamental in physics, representing quantities with both

20 questions laddered from warm-up to topper-level, each with an explanation. A taste:
What is the solution to the equation $2x + 3 = 11$?
Beginnerx = 4
Subtract 3 from both sides gives $2x = 8$, then divide by 2 to get $x = 4$.
Which of the following is a linear equation in one variable?
Beginner$3x - 7 = 2x + 1$
A linear equation in one variable has the form $ax + b = 0$; $3x - 7 = 2x + 1$ simplifies to $x - 8 = 0$.
Solve for $y$: $5y - 2 = 3y + 6$
Intermediatey = 4
Subtract $3y$ from both sides: $2y - 2 = 6$; add 2: $2y = 8$; divide by 2: $y = 4$.
What is the slope of the line represented by $y = -3x + 5$?
Beginner-3
In slope-intercept form $y = mx + b$, $m$ is the slope, so $m = -3$.
