1. What is the Distance Formula?

The distance formula calculates the straight-line distance between two points in a Cartesian coordinate system. It is derived from the Pythagorean theorem and is fundamental in geometry, physics, and engineering applications.

2. How Does the Calculator Work?

The calculator uses the distance formula:

Where:

• \( x_1, y_1 \) — Coordinates of the first point
• \( x_2, y_2 \) — Coordinates of the second point

Explanation: The formula calculates the hypotenuse of a right triangle formed by the differences in x and y coordinates between the two points.

3. Importance of Distance Calculation

Details: Distance calculation is essential in various fields including navigation, computer graphics, physics, engineering, and geographic information systems (GIS). It forms the basis for more complex geometric calculations.

4. Using the Calculator

Tips: Enter the coordinates of two points in meters. The calculator will compute the straight-line distance between them. All values must be valid numerical inputs.

5. Frequently Asked Questions (FAQ)

Q1: Can this calculator handle 3D coordinates?
A: No, this calculator is specifically designed for 2D coordinates. For 3D distance calculation, you would need to use a different formula that includes the z-coordinate.

Q2: What units does the calculator use?
A: The calculator uses meters as the default unit, but the formula works with any consistent unit of measurement.

Q3: How accurate is the calculation?
A: The calculation is mathematically precise based on the inputs provided. The result is rounded to 4 decimal places for readability.

Q4: Can I use negative coordinates?
A: Yes, the distance formula works with both positive and negative coordinate values as it uses the squared differences.

Q5: 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 straight-line distance between start and end points with direction.
