The gravitational attraction depends on masses, electrical attraction depends on opposite charges, and magnetic attraction depends on currents going in the same direction. The gravitational force is the only force that is purely attractive. Electricity and magnetism can be repulsive as well.
Is the force attractive or repulsive?
The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.
Is force of attraction always attractive?
We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any.
Why are forces repulsive?
Repulsive force may refer to: A repulsive force of an accelerating universe, which according to certain theories causes planets and matter to get farther and farther apart. Like charges repelling according to Coulomb’s law. Repulsive force (magnetism) between magnets of opposite orientation.
What is an repulsive force?
Definitions of repulsive force. the force by which bodies repel one another. synonyms: repulsion. Antonyms: attraction, attractive force. the force by which one object attracts another.
Is electromagnetic attractive or repulsive?
Electromagnetism is both an attractive and repulsive force between particles with a property called charge, which come in two varieties – positive and negative. Objects of like charge will have a repulsive effect on each other, while objects of unlike charges will have an attractive effect.
Are electromagnetic forces attractive or repulsive?
Electromagnetic force is a special force that affects everything in the universe because it has an infinite-range attractive, like gravity; it is also a repulsive force which acts between charged particles.
Can gravitational force be attractive or repulsive?
Both in the Newton theory of gravitation and in the General Theory of Relativity the gravitational force is exclusively attractive one. However, the quantization of gravity shows that the gravitational forces can also be repulsive .
How do you find the force of attraction?
The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.
What force occurs when ions create attractive and repulsive forces?
Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule.
Which is a force that attracts any two pieces of matter in the universe?
Gravity is an attractive force, one that attracts all of the matter in the Universe towards all of the other bits of matter in the Universe. On the size scale of moons, planets, stars, and galaxies, it is an extremely important force, and governs much of the behavior of these objects.
Which force is attractive?
The gravitational force is the only force that is purely attractive. Electricity and magnetism can be repulsive as well. For all three forces, the closer the objects are to each other, the stronger the force of attraction. When the objects are far apart, the force of attraction is weaker.
What is force attraction?
a force between two bodies, molecules, particles, or the like, that attracts each to the other. … Gravity is the force of attraction between two bodies that have mass.
Is force of attraction negative?
In general when the force is attractive, the potential energy is negative and as shown above force will be negative. In case of repulsion, with the same argument, the force will be positive.
