Attraction is a force between two or more dissimilar or unlike charges. Two charges of dissimilar characteristics pull towards each other. Repulsion is a force between two or more similar or like charges. Two charges of similar characteristics pull away from each other.

What does repulsive mean in physics?
repulsion. / (rษชหpสlสษn) / noun. a feeling of disgust or aversion. physics a force tending to separate two objects, such as the force between two like electric charges or magnetic poles.
What causes repulsion?
In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.
What is repulsive in science?
Repulsion definition (physics) The force that causes particles or bodies to repel one another, as from having the same electric charge or magnetic polarity. noun. 11. 1. The act of repulsing or the condition of being repulsed.
How do you know if its repulsion or attraction?
If both the interacting particles are positively or negatively charged, then the force is repulsive. If both the interacting particles are of opposite charges then the force is attractive in nature.
What is an example in attraction and repulsion?
For example, the force between two parallel wires carrying currents in the same direction is attractive. It is repulsive if the currents are in opposite directions.
What is the define of repulsion?
Definition of repulsion 1 : the action of repulsing : the state of being repulsed. 2 : the action of repelling : the force with which bodies, particles, or like forces repel one another. 3 : a feeling of aversion : repugnance.
What is a repulsion 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.
What is repulsion effect?
The attentional repulsion effect refers to the perceived displacement of a Vernier stimulus in a direction that is opposite to a brief peripheral cue.
Why does repulsion increase energy?
As the atoms near each other, their outer (valence) electrons interact to repel each other, and this repulsion energy increases very rapidly as the distance r decreases.
What is an example of a repulsive force?
Repulsive force (magnetism) between magnets of opposite orientation. A compressed material repelling bodies on both sides, e.g. according to Hooke’s law. Repulsive force (biology), associated with involuntarily vomiting, as in response to ingestion of a toxin.
Is gravity a repulsive force?
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 [3].
What is magnetic repulsion?
When two opposite magnetic poles are close, they attract each other. When like poles are pushed together, there is a force of repulsion. The rule for magnets is that like poles repel and unlike poles attract. Magnetic force in action.
Is magnetic attraction stronger than repulsion?
The attraction between magnets is a little stronger than the repulsion. That is due to the alignment of the molecular magnets in the magnet. The attraction as well as the repulsion of magnets decrease significantly with increasing distance.
What is the law of attraction and repulsion in magnetism?
The law states that the force of attraction or repulsion between two magnetic poles is directly proportional to the product of the strengths of the poles and inversely proportional to the square of the distance between them.
Why attraction is more than repulsion?
For the same distance, the force of attraction between unlike charges and the force of repulsion between like charges is the same. The attraction as well as the repulsion decreases with the increase in the distance between the two charges.
Does repulsion increase potential energy?
We know that by F=โdU/dx formula that when force is attractive in nature potential energy increases and when force is repulsive, potential energy decreases.
Why repulsive force is positive?
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.
What is the force of attraction and repulsion called?
The force of attraction or repulsion between two charged bodies is called gravitational force.
Is repulsion a push or a pull?
Solution : Repulsion means moving away from each other. When things move away from each other, it is a push.
What is repulsion in electric charge?
When two positively or two negatively charged particles come closer to each other then they repel from each other. Then it is known as electrostatic repulsion.
What is repulsion synonym?
antipathy. nounstrong dislike, disgust. abhorrence. allergy. animosity.
What is attraction in science?
(1) The act, capacity, or tendency to attract. (2) The process between objects being drawn towards each other. (3) The electric or magnetic force from a body or particles that draws another towards it; the force holding the particles together.
What is the spelling for repulsion?
repulsion noun [U] (DISLIKE)
Is repulsive force negative?
When the charges have opposite sign, the force is attractive (negative F), while if both charges have the same sign, the force is repulsive (positive F).
