The Universal Gravitation Calculator determines the gravitational force between two masses separated by a certain distance. It applies Newton’s Law of Universal Gravitation, using the formula F = G × (m₁ × m₂) / r², where G is the gravitational constant (6.674×10⁻¹¹ N·m²/kg²). This tool helps visualize how mass and distance influence gravitational attraction, making it an excellent resource for physics learners and professionals.
