Why attractive force is more than repulsive force?

Why is the magnitude of the potential energy of attractive forces more than for repulsive forces? – Quora. It is due to the fundamental relation of P.E. for the attractive/repulsive force having inverse mathmetical relationship to the distance between the objects.

Why is force of attraction greater than force of repulsion?

It is due to the fact that the closer the two objects are, the stronger the force. So if two things are attracted to each other, they will be increasing in force as they get closer; whereas, if they are repelling, the force becomes slightly weaker due to the larger distance between the two objects.

Are attractive forces greater than repulsive forces?

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. Remember that the lower potential energy increases the stability of the system.

Is attractive force equal to repulsive force?

c) At bond length attractive forces equal repulsive forces; energy is at its minimum.

What is the difference between attractive and repulsive force?

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. Because the nuclei are positive and the electrons are negative, the electrons are attracted to the nuclei.

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. … This increase in energy as atoms are crowded together is called steric repulsion or steric hindrance.

Why are attractive forces negative?

That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational …

What are the attractive and repulsive forces between atoms?

The covalent bonds formed are also known as the molecular bond. The force of attraction or repulsion between the two atoms when they share a pair of electrons are known as covalent bonding. The covalent compounds are formed by two or more nonmetals atoms.

Is proton proton attractive or repulsive?

The protons in a nucleus have two forces to contend with, the electromagnetic force which is repulsive as you suggest, and also the strong nucleon-nucleon force which is not only attractive but also much stronger than the other.

What are the repulsive and attractive forces involved in a covalent bond?

The modern covalent bond is conceived to be a region of high electron density between two positively charged atomic nuclei such that nucleus-nucleus repulsion is negated, and a net attractive forces results from electrostatic interaction between the positively charged nuclei, and the negatively charged electron cloud.

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.

Is gravitational force attractive or repulsive?

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

Is strong nuclear force attractive or repulsive?

The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 1.0 × 1015 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At distances less than 0.7 fm, the nuclear force becomes repulsive.

What is an attractive force and its importance?

attractive force – the force by which one object attracts another. attraction. affinity – (immunology) the attraction between an antigen and an antibody. bond, chemical bond – an electrical force linking atoms.
