What it calculates
The “Tide Force” calculator computes Tidal acceleration in µm/s² from 3 parameters: mass of the attracting body (M⊕), center-to-center distance (km), radius of the body experiencing the tide (km).
An astronomy calculation for enthusiasts and scientists.
Example calculation
With parameters Mass of the attracting body = 0.0123 M⊕, Center-to-center distance = 384,400 km, Radius of the body experiencing the tide = 6,371 km the result is 1.1 µm/s² (a = 2GMR/d³ (approximation d ≫ R)).
How to use
- Enter mass of the attracting body, center-to-center distance and radius of the body experiencing the tide — each field above is adjustable with a slider.
- Tidal acceleration (µm/s²) is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.
