What two properties of particles influence the force strength of attraction or repulsion?
The attraction or repulsion between charged particles is called electric force. The strength of electric force depends on the amount of electric charge on the particles and the distance between them. Larger charges or shorter distances result in greater force.
How do photons cause attraction?
Since the wave is everywhere, the photon can be created by one particle and absorbed by the other, no matter where they are. If the momentum transferred by the wave points in the direction from the receiving particle to the emitting one, the effect is that of an attractive force.
How do particles attract?
Gravity is the force that all objects with mass exert upon one another, pulling the objects closer together. There are several kinds of forces that particles can exert on one another. These forces can cause one particle to attract, repel, or even destroy another particle.
Which state of matter has the weakest attractive force?
Solid
Solid. The gaseous state has weakest intermolecular forces of attraction and so their molecules are away from each other.
Why is attractive force 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 force can act between two photons?
The electromagnetic force, also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract one another, while like charges repel. The greater the charge, the greater the force.
Can virtual photons be detected?
These photons are “virtual”; that is, they cannot be seen or detected in any way because their existence violates the conservation of energy and momentum. The photon exchange is merely the “force” of the interaction, because interacting particles change their speed and direction of travel as they release…
What two particles attract each other?
The two subatomic particles that are attracted to each other are protons and electrons.
What particles are very far apart?
Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.
