1. What is Distance Between Surfaces?

Distance between surfaces refers to the actual gap or separation between the outer surfaces of two spherical bodies. It represents the shortest distance that would exist if the two spheres were brought close to each other without touching.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( r \) — Distance between surfaces (m)
• \( z \) — Center-to-center distance (m)
• \( R_1 \) — Radius of spherical body 1 (m)
• \( R_2 \) — Radius of spherical body 2 (m)

Explanation: The formula subtracts the radii of both spherical bodies from the center-to-center distance to determine the actual gap between their surfaces.

3. Importance of Distance Calculation

Details: Calculating the distance between surfaces is crucial in various fields including physics, engineering, and materials science. It helps determine interaction distances, clearance requirements, and spatial relationships between spherical objects in systems and structures.

4. Using the Calculator

Tips: Enter center-to-center distance and both radii in meters. All values must be positive numbers, and the center-to-center distance should be greater than or equal to the sum of the two radii for a valid result.

5. Frequently Asked Questions (FAQ)

Q1: What happens if the center-to-center distance is less than the sum of radii?
A: This would indicate that the spheres are overlapping or intersecting, which is physically impossible for solid spheres. The calculator will show a negative result indicating overlap.

Q2: Can this formula be used for non-spherical objects?
A: No, this formula is specifically designed for spherical bodies. For other shapes, different geometric calculations are required.

Q3: What units should be used for input values?
A: The calculator uses meters as the default unit, but any consistent unit system can be used as long as all inputs are in the same units.

Q4: How accurate is this calculation?
A: The calculation is mathematically exact for perfect spheres. The accuracy depends on the precision of your input measurements.

Q5: What applications use this distance calculation?
A: This calculation is used in molecular physics, astronomy, mechanical engineering, nanotechnology, and various other fields where spherical objects interact or are arranged in space.
