Mathematical Explanation

The gravitational force is calculated using Newton's Law of Universal Gravitation:

F = G * (m1 * m2) / r²

Where:

  • F is the gravitational force in Newtons (N)
  • G is the gravitational constant (6.674 × 10⁻¹¹ N(m/kg)²)
  • m1 and m2 are the masses of the two objects in kilograms (kg)
  • r is the distance between the centers of the masses in meters (m)

Example Calculations

Example 1: Earth and Moon

Given:

  • Mass of Earth (m1) = 5.97 × 10²⁴ kg
  • Mass of Moon (m2) = 7.34 × 10²² kg
  • Distance (r) = 384,400,000 m

Calculation:

F = (6.674 × 10⁻¹¹) * ((5.97 × 10²⁴) * (7.34 × 10²²)) / (384,400,000)²
F ≈ 1.98 × 10²⁰ N
Example 2: Two people

Given:

  • Mass of person 1 (m1) = 70 kg
  • Mass of person 2 (m2) = 65 kg
  • Distance (r) = 1 m

Calculation:

F = (6.674 × 10⁻¹¹) * (70 * 65) / (1)²
F ≈ 3.04 × 10⁻⁷ N
