  4. The range of objects and phenomena studied in physics is immense. From the incredibly short lifetime of a nucleus to the age of the Earth, from the tiny sizes of sub-nuclear particles to the vast distance to the edges of the known universe, from the force exerted by a jumping flea to the force between Earth and the Sun, there are enough factors of 10 to challenge the imagination of even the ...

  5. Feb 20, 2022 · Coulomb’s law gives the magnitude of the force between point charges. It is F = k|q1q2| r2, where q1 and q2 are two point charges separated by a distance r, and k ≈ 8.99 × 109N ⋅ m2 / C2. This Coulomb force is extremely basic, since most charges are due to point-like particles.

  6. The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere. Named for the 18th–19th-century French.
