k is the Boltzmann Constant (= 1.3806488(13)×10 -23)īased on the primary assumptions that the volume of atoms or molecules is negligible, compared to the container volume and the attractive forces between molecules are negligible, the kinetic theory describes the properties of ideal gases.Let’s begin with the prime ideal gas laws and the equation of state of an ideal gas. Here are some of the most important physics formulas and equations, associated with ideal gases. The resulting equations and laws of an ideal gas conform with the nature of real gases under certain conditions, though they fail to make exact predictions due the interactivity of molecules, which is not taken into consideration. Here are some of the most important formulas associated with classical thermodynamics and statistical physics.Īn ideal gas is a physicist’s conception of a perfect gas composed of non-interacting particles which are easier to analyze, compared to real gases, which are much more complex, consisting of interacting particles. It’s a field focused on studying matter and energy in all their manifestations. Thermodynamics is a vast field providing an analysis of the behavior of matter in bulk.

Inductance of a cylindrical air core Coil (L) = (m 0KN 2A / l) Where, L is inductance and I is the current flowing through the inductor. Here are some important formulas associated with inductors.Įnergy Stored in Inductor (E stored) = 1/2 (LI 2) This property of inductance, in these devices, is caused by the electromotive force, created by magnetic field induced in them.

ε 0 = Permittivity of Free Space (= 8.85 × 10 -12 C 2 / Nm 2)Īn inductor is an electrical component which resists the flow of electrons or electric current through it.

k = dielectric constant (k = 1 in vacuum).

V is the potential difference across the capacitor.

Q is the charge stored on each conductor in the capacitor.

Unit of capacitance is Farad (F) and its values are generally specified in mF (micro Farad = 10 -6 F).Įnergy Stored in a Capacitor (E cap) = 1/2 CV 2= 1/2 (Q 2 / C) = 1/2 (QV)Ĭurrent Flowing Through a Capacitor I = C (dV / dt)Įquivalent capacitance for ‘n’ capacitors connected in parallel:Ĭ eq (Parallel) = C 1 + C 2 + C 3…+ C n = Σ i=1 to n C iĮquivalent capacitance for ‘n’ capacitors in series:ġ / C eq (Series) = 1 / C 1 + 1 / C 2…+ 1 / C n = Σ i=1 to n (1 / C i) Here are the most important formulas related to capacitors. A typical capacitor consists of two conductors separated by a dielectric or insulating material. So here is the promised list which will help you out.įor n number of resistors, R 1, R 2…R n, the formula will be:ġ/ R eq = 1/ R 1 + 1/ R 2 + 1/ R 3…+ 1/ R n CapacitorsĪ capacitor stores electrical energy, when placed in an electric field. The joy of having solved a physics problem on your own, is worth all the effort! Understanding physics concepts challenges your imagination and thinking potential, wherein, if you visualize a problem, then you can come up with a solution. Our physics formulas list is aimed at helping you out in solving problems.

If you don’t wish to think on your own and apply basic physics principles, solving physics problems is always going to be tough. Physics has a reputation for being difficult and to some extent that’s true, due to the mathematics involved.

Physics help is provided here in the form of ready to use formulas. Study physics and look at it as an opportunity to appreciate the underlying beauty of nature, expressed through natural laws. Physics Formulasĭerive all these formulas once, before you start using them. This ScienceStruck article lists some physics formulas that you would need in solving basic physics problems. If you understand the physical concepts underlying those formulas, deriving them or remembering them is easy.

Try to understand what a formula says and means, and what physical relation it expounds. I would say that there is a lot more to ascertain than just remember and mug up the physics formulas. Learning physics is basically studying the fundamental laws that govern our universe. It is also one of the toughest sciences to master. Physics is the most fundamental of all sciences.
