sci.gravitational-force Calculator
Calculates gravitational force between two masses using Newton's universal law F = Gm₁m₂/r². G = 6.674 × 10⁻¹¹ N·m²/kg² — gravity is the weakest of the four fundamental forces yet dominates at planetary scales due to its infinite range and always-attractive nature.
Inputs
M1
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
M2
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
R
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Alt
Reference formula or conversion factor shown for context.
Results
gravitational force (N)
The value at the specified point or condition.
acceleration on m2 (m/s²)
The proportional relationship between two quantities.
escape velocity (km/s)
Reference formula or conversion factor shown for context.
surface g (m/s²)
Reference formula or conversion factor shown for context.
orbital period (hrs)
Reference formula or conversion factor shown for context.
F=Gm₁m₂/r²
