Repulsion is a movement between two charges that are identical or similar. The power that exists between two electrons (negative charge). Attraction is a force between two charges that are distinct or unlike. … Repulsive forces occur only when atoms are very close to each other.
What is repulsive force in physics?
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 an attractive force?
Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.
What are some repulsive forces?
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.
What is repulsive force Class 11?
Repulsion is’ a movement between two charges that are identical or similar. The force of two electrons between them (negative charge). … ‘ The two charges of a different type draw against one another.
What are attractive intermolecular forces?
There are several types of attractive intermolecular forces: Dipole-dipole forces, London dispersion forces, Hydrogen bonding, and. Induced-dipole forces.
How do you know if a force is attractive or repulsive?
If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.
What is the attractive force between atoms?
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.
What is repulsive force?
The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. … If the charges have the same sign, the electrostatic force between them is repulsive; if they have different signs, the force between them is attractive.
Is electromagnetic force 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.
Which bond is balanced attractive and repulsive forces between atoms?
Description of chemical bond Chemical bond involves only attraction between atoms. (12/14) “It is a matter of attraction. The electrons are attracted to the nuclei because the nuclei are positive and the electrons are negative.” Chemical bond involves both attraction and repulsion forces.
Are intermolecular forces attractive or repulsive?
Intermolecular forces are repulsive at short distances and attractive at long distances (see the Lennard-Jones potential). In a gas, the repulsive force chiefly has the effect of keeping two molecules from occupying the same volume.
Why attractive force is more than repulsive force?
One is that the single electrons that each hydrogen atom possesses begin to repel each other. … As the atoms first begin to interact, the attractive force is stronger than the repulsive force and so the potential energy of the system decreases, as seen in the diagram.
