Distance Formula:
From: | To: |
The distance formula calculates the straight-line distance between two points in a coordinate plane. It is derived from the Pythagorean theorem and provides the shortest path between any two points in 2D space.
The calculator uses the distance formula:
Where:
Explanation: The formula calculates the horizontal and vertical differences between points, squares them, sums the squares, and takes the square root to find the straight-line distance.
Details: Distance calculation is fundamental in mathematics, physics, engineering, computer graphics, navigation systems, and geographic information systems (GIS). It's used for route planning, collision detection, and spatial analysis.
Tips: Enter the coordinates of both points in the same unit system. The calculator accepts decimal values for precise calculations. Ensure all four coordinates are provided for accurate results.
Q1: Can this calculator handle negative coordinates?
A: Yes, the distance formula works with both positive and negative coordinates in any quadrant of the coordinate plane.
Q2: What units does the distance result use?
A: The distance is returned in the same units as your input coordinates. If you enter coordinates in meters, the distance will be in meters.
Q3: Can this formula be extended to 3D space?
A: Yes, for 3D coordinates, the formula becomes: \( Distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2} \)
Q4: What's the difference between distance and displacement?
A: Distance is a scalar quantity representing the total path length, while displacement is a vector quantity representing the shortest path between start and end points with direction.
Q5: How accurate is this calculation?
A: The calculation is mathematically exact for the given coordinates. Accuracy depends on the precision of your input values and the coordinate system used.
