Scalars vs Vectors
Distinguish between quantities with magnitude only and those with both magnitude and direction.
Foundations & Tools · Topic
Scalars & Vectors
Represent physical quantities in 2D and 3D so you can analyze real systems using clean, consistent vector notation.
← Back to Foundations & ToolsVector Components (2D & 3D)
Break vectors into components using geometry and unit vectors for efficient calculations.
Vector Addition & Subtraction
Add and subtract vectors graphically and analytically using components.
Unit Vectors
Use unit vectors to express directions cleanly and simplify vector equations.
Dot Product (Scalar Product)
Learn how dot products connect vectors to work, projections, and angles between directions.
Cross Product (Introductory)
Introduce the vector product and its role in torque, angular momentum, and magnetic forces.
