sci.tidal-force Calculator
Calculates the differential tidal force across a body from a distant mass using Ftidal = 2GMmr/d³. Moon's tidal force is 2.2× stronger than the Sun's at Earth's surface despite Sun's greater mass — tidal force scales as 1/d³ favouring the nearer body.
Inputs
M Kg
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
M Kg
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
R M
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Dr M
Reference formula or conversion factor shown for context.
Results
tidal acceleration (m/s²)
The proportional relationship between two quantities.
tidal force on 1 kg (N)
Sample size or count used in the calculation.
a_tidal = 2GMΔr/R³
Reference formula or conversion factor shown for context.
ratio to surface gravity
The proportional relationship between two quantities.
Earth-Moon tidal effect
Sample size or count used in the calculation.
