Fundamental physical constants are special values used in models of the physical universe. These constants include the speed of light, the gravitational constant, and Planck’s constant. They are considered “fundamental” because they are derived thru measurement rather than theoretical calculation.

These constants are frequently used in solving physics problems. If these constants were even slightly different, the universe might not be capable of supporting life. ISAAC Newton believed a “cosmic clockmaker” set these parameters.

One of the most basic of these numbers is the electric constant, k.This constant allows scientists to calculate the forces between electric charges. This is significant because all matter is made of electrons, neutrons, and protons, two of which carry an electric charge. The interaction between electrons is what forms molecules. Without it, everything would be an undifferentiated soup.

But how do scientists determine the value of the electric constant? What is its relationship to other fundamental constants? And is it truly fundamental?

coulomb’s Law and Constant

Electric charge refers to an imbalance in the number of protons and electrons in an object. If a clothes dryer removes electrons from socks, the socks become positively charged. If they gain electrons, they become negatively charged. Protons cannot be removed from the nucleus of an atom without causing a nuclear reaction.

Objects with opposite charges attract each other, while objects with the same charge repel. To demonstrate this, place a piece of clear tape on a smooth table, then place a second piece on top. Pull them off together, then separate them. One will be positive and the other negative, and they will bend toward each other when held in proximity.

Repeating this process will create two positive and two negative tapes. Holding two tapes with similar charges near each other will demonstrate repulsion.

The interaction between electrons is what forms molecules to create you and everything around you.Otherwise it would all be just some undifferentiated soup.
