Frequently Asked Questions — Distance Calculator (Points)
What is the distance formula?
The distance between two points (x₁,y₁) and (x₂,y₂) is d = √((x₂−x₁)² + (y₂−y₁)²). This comes from the Pythagorean theorem: the distance is the hypotenuse of a right triangle with legs Δx and Δy. In 3D: d = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²).
How do I find the distance in 3D?
The 3D distance formula extends the 2D formula with a third dimension: d = √(Δx² + Δy² + Δz²). For points (1,2,3) and (4,6,3): Δx=3, Δy=4, Δz=0, d=√(9+16+0)=√25=5.
What is the difference between distance and displacement?
Distance is the scalar length of the path between points — always positive. Displacement is a vector: the straight-line change from start to end with direction. The distance formula gives the straight-line (Euclidean) distance, which equals displacement magnitude.
