What affects the force of attraction?
The force of gravitational attraction is proportional to the product of the masses, m1 and m2, and is inversely proportional to the square of the distance between the two masses, represented by r.
What is the relationship between force and attraction?
All objects attract each other with a force that is directly proportional to the product of their masses and inversely proportional to their distance of separation.
How does the force of attraction between two bodies depends on the masses and distance between them?
The gravitational force is directly proportional to the product of the masses of two bodies and inversely proportional to the square of the distance between them. … So, two bricks tied together will not fall faster than a single brick under the action of gravity.
How does force of attraction increase?
The force of this attraction is proportional to the size of charge and inversely proportional to the distance between the charges. As we go down a group the distance between the nucleus and valence electrons increases, while the charges involved stay the same.
What does force of attraction mean?
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.
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.
Which force is always a force of attraction?
Why Is Gravity Force An Attractive Force Rather Than Repulsive? 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.
What is the force of attraction in solid?
Solid In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place.
On which of the following the gravitational force between two objects does not depend?
Gravitational force does not depend upon size and shape of objects.
What is Newton’s Universal Law of gravitation give the mathematical expression for it?
The mathematical equation for the law is given as, F = G m m r m 1 m 2 r 2 where G is universal gravitational constant, m1 and m2 are masses and r is the distance between two masses.
What is the value of G on Jupiter?
Calculating g on Other Planets
|Planet||Radius (m)||g (m/s2)|
|Mercury||2.43 x 106||3.61|
|Venus||6.073 x 106||8.83|
|Mars||3.38 x 106||3.75|
|Jupiter||6.98 x 107||26.0|
Why is the force of attraction important in chemistry?
Intermolecular forces of attraction
Intermolecular forces are much weaker than the intramolecular forces of attraction but are important because they determine the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization.
What is the force of attraction chemistry?
When two atoms are brought together and as the distance between them becomes comparable with their dimension, the positive and negative charges of each atom start influencing charges in the other atom. This gives rise to an interatomic force and changes the total energy of the pair.
Why does the force of attraction increase across a period?
Across the period the Atomic radii decreases
The electron repulsion is balanced by the nuclear charge attractions, and as the nuclear charge gets larger, so the electrons get closer together. The net attractive electrostatic attraction is increased as the nuclear charge increases.
