🔬 Practical Example

Let’s simulate the gravitational force between Earth and the Moon:

• Mass 1 (Earth): 5.97e24 kg
• Mass 2 (Moon): 7.35e22 kg
• Distance: 3.84e8 meters
• Gravitational Constant (G): 6.67430e-11 N·m²/kg²

After calculation, the result:

• Force of Gravity (F): ≈ 1.98e20 N
• Mass 1: 5.970e+24 kg
• Mass 2: 7.350e+22 kg
• Distance: 3.840e+08 m

This result aligns with the gravitational force that keeps the Moon in orbit around Earth.
