Coulombic and gravitational forces both describe interactions between masses or charges, but they operate under different principles. The Coulombic force is governed by electric charges and is described by Coulomb's law, while the gravitational force acts between masses and is defined by Newton's law of universal gravitation. Both forces are inversely proportional to the square of the distance between the interacting entities, indicating that they weaken with increasing distance. Despite their differences, both forces are fundamental interactions that follow similar mathematical forms, highlighting their shared characteristics. Understanding these forces is crucial for comprehending various physical phenomena.
