Understanding how far an object has traveled or its net movement is essential in physics, navigation, sports, and everyday life. The Distance & Displacement Calculator is a versatile tool that helps you calculate both distance—the total path length—and displacement—the shortest straight-line distance between two points. With multiple modes including 2D, 3D, multi-point paths, and velocity-based calculation, this tool provides precise measurements along with directional information.

Example Scenario
Scenario 1: 2D Point Movement
Suppose a student moves from point A (0,0) to point B (3,4):
- Distance = √((3-0)² + (4-0)²) = 5 units
- Displacement = 5 units
- Direction = 53.13° (NE)
The calculator displays the distance in meters, kilometers, miles, or feet, along with Δx = 3 and Δy = 4.
Scenario 2: Multi-Point Path
A hiker follows a trail: (0,0) → (2,3) → (5,7)
- Total Distance = √(2²+3²) + √(3²+4²) = 5 + 5 = 10 units
- Displacement = √((5-0)² + (7-0)²) ≈ 8.6 units
- Direction = 54.46° (NE)
The interpretation notes the hiker followed a non-linear path, so distance > displacement.
Scenario 3: Velocity & Time
A drone moves at 10 m/s for 20 seconds at a 45° angle:
- Distance = 10 × 20 = 200 m
- Displacement = 200 m
- Δx = 141.42 m, Δy = 141.42 m
- Direction = 45° (NE)
This mode is useful for motion studies or simulation analysis.
