What does it mean if a force is attractive?

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 makes a force attractive?

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. … The Coulomb force F on a charged particle due to another charge can be obtained by multiplying the electric field caused by by the charge .

Is there an attractive force?

There are two kinds of attractive forces shown in this model: Coulomb forces (the attraction between ions) and Van der Waals forces (an additional attractive force between all atoms).

What is the name of attractive force?

The correct answer is Option (1) i.e. ​Gravitational force. Gravitational force: The gravitational force (F) is a force that attracts any two objects with a mass within a universe.

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.

Why is the force of attraction negative?

You would have learnt this thing in chemistry (In Atom Structure, you would have calculated energy of electrons for different energy levels b/w electron & proton(nucleus)), that attractive force reduces the energy of the electrons and repulsive force increases the energy of electrons) So since energy corresponding to …

Are attractive forces positive or 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).

What is vanderwall force of attraction?

van der Waals forces, relatively weak electric forces that attract neutral molecules to one another in gases, in liquefied and solidified gases, and in almost all organic liquids and solids. … The tendency of such permanent dipoles to align with each other results in a net attractive force.

What is the force attraction between two objects?

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.

What is electrostatic force attraction?

Electrostatic forces are attractive or repulsive forces between particles that are caused by their electric charges. This force is also called the Coulomb force or Coulomb interaction and is so named for French physicist Charles-Augustin de Coulomb, who described the force in 1785.

Which of the following is correct order of force of attraction?

The forces of attraction are the strongest in solids, followed by liquids and the weakest in gases. Oxygen is a gas, water is a liquid and sugar is a crystalline solid. So the increasing order of forces of attraction is Oxygen < Water < Sugar.

What is the name of attractive force which acts between any two bodies in our universe?

Gravitational force is the force of attraction between any two bodies in the universe.

What is gravitational attraction?

Definitions of gravitational attraction. (physics) the force of attraction between all masses in the universe; especially the attraction of the earth’s mass for bodies near its surface. synonyms: gravitation, gravitational force, gravity.
