Tidal force Calculator

Calculate the gravitational and tidal forces of the moon and the sun, and their respective ratios of those at apogee to those at perigee.

Tidal force
Moon's mass
    1. kg
distance
    1. km,
    2. eccentricity
Sun's mass
    1. kg
distance
    1. km,
    2. eccentricity
Earth's mass
    1. kg,
    2. radius
    3. km

Gravity is inversely proportional to the square of the distance, and tidal power is the cube of the distance.
The tidal force of the moon is about 2.2 times larger than that of the sun.
The ratio of the tidal force of the apogee and perigee is about 1.4 by the elliptical orbit of the moon.
