Unformatted text preview: exerted by one object on another object even though there is no physical contact between them There are some important similarities and differences between electrical and gravitational forces Electrical Force Compared to Gravitational Force Both are inverse square laws The mathematical form of both laws is the same Masses replaced by charges Electrical forces can be either attractive or repulsive Gravitational forces are always attractive Electrostatic force is stronger than the gravitational force...
