Gravitational Force Calculator

Find the gravitational attraction between two masses.

Mass 1

Mass 2

Distance

Calculated Output

Gravitational force (N) 687.4

Formula: F = G·m₁·m₂ ÷ r²

Step-by-Step Breakdown

1. Values used:

2. Mass 1 = 5.972e+24

3. Mass 2 = 70

4. Distance = 6,371,000

6. Gravitational force = 687.4N

Did this calculator solve your problem today?

The math behind it

F = G × m₁ × m₂ ÷ r², with G = 6.674 × 10⁻¹¹.

Earth & a 70 kg person at Earth's radius → ~687 N.

Why so weak between everyday objects?

G is tiny, so gravity only becomes large with planet-sized masses.
