1. Scalar Multiplication (kA⃗)

Multiplies a vector by a real number (scalar). Changes magnitude; reverses direction if k < 0.

Result: Vector in same/opposite line

Type of Result: 2D/3D Vector

Physical Example: p⃗ = m v⃗ (Momentum) or F⃗ = m a⃗

2. Dot Product (A⃗ · B⃗)

Measures how much A⃗ and B⃗ point along each other: |A||B| cos θ.

Result: Scalar Number

Type of Result: Scalar Quantity

Physical Example: Work W = F⃗ · s⃗, Electric Flux Φ = E⃗ · A⃗

3. Cross Product (A⃗ × B⃗)

Measures perpendicularity & rotational effect: |A||B| sin θ n̂.

Result: 3D Orthogonal Vector

Type of Result: Vector ⊥ to Plane

Physical Example: Torque τ⃗ = r⃗ × F⃗, Magnetic Force F⃗ = q(v⃗ × B⃗)
