Planck's constant h %3D 6.63 × 10−34 J, s %3D 4.136 × 10-15 eV, s. Among the popular **physical** formulas, Ohm's Law is explained as the current (I) passing through a conductive material is directly proportional to the potential difference (V) between the two ends of the conductor. If you resort to using all these formulas, you can pass the exams, but you won't dedicate yourself to real physics. This blog aims to provide you with a complete list of basic Physics formulas that you should know in order to pass the competitive exam of your choice.

While you must strengthen your basic formulas in Physics, it is also imperative to analyze the fundamental concepts of this subject. If you don't want to think on your own and apply the basic principles of physics, solving physics problems is always going to be difficult. These are the key points to remember in SI units along with the basic physical formulas mentioned above. This ScienceStruck article lists some physics formulas that you would need to solve basic physics problems.

This is the lens manufacturer's formula, which can help you calculate the focal length of a lens based on its physical parameters. To solve all these types of challenges, which are presented in the form of questions, it is necessary to have an adequate understanding of the subject of the formulas of Physics, as well as their concepts. If you understand the physical concepts that underlie those formulas, it's easy to derive or remember them. These are some of the most important formulas associated with classical thermodynamics and statistical physics.
