The Essential Physics Formulas You Need to Know

If you want to pass your competitive exams, you need to have a good understanding of the basic physics formulas. This blog post provides a comprehensive list of the essential physics formulas that you should know in order to ace your exams. It is not enough to simply memorize the formulas. You must also understand the fundamental concepts of physics in order to solve problems.

If you don't think for yourself and apply the basic principles of physics, it will be difficult to solve physics problems. In addition to Planck's constant h = 6.63 × 10−34 J, s = 4.136 × 10-15 eV, s and Ohm's Law (I = V/R), here are some other key points to remember in SI units:

  • Lens Manufacturer's Formula: 1/f = (n-1)[(1/R1) - (1/R2)]
  • Classical Thermodynamics Formulas: PV = nRT, U = q + w
  • Statistical Physics Formulas: S = k ln W, F = -kT ln Z
If you understand the physical concepts that underlie these formulas, it will be easier to remember or derive them. With this knowledge, you can solve any challenge presented in the form of a question.
