Gravity is always attractive or repulsive

WebFeb 5, 2024 · Another major difference between the two forces is that gravitational force can only be attractive, whereas electrostatic could be attractive or repulsive, depending on the sign of charges; unlike charges attract and like charges repel. Is the force between two masses always attractive can it ever be repulsive? Web1. Gravity acts between any two objects, magnetism only between some. 2. Gravity is always attractive, magnetism is sometimes repulsive. 3. At large distances the gravitational force falls off inversely with the distance squared. The magnetic force falls off at large distances at least as fast as inversely with the distance to the fourth power. 4.
