Physics Formulas - List of all Physics Formulas

The subject of Physics is all about articulating things with real values and not memorizing them time and again. During the time of application, we may come across many concepts, problems and mathematical formulas. With these, we have to use our ability as well as creativity and good sort of potential to find solutions to the mentioned problems. Here we will have some basic physics formulas with examples. Download the Chapter wise Important Math Formulas and Equations to Solve the Problems Easily and Score More Marks in Your CBSE Board Exams.

Physics Formulas

The understanding of concepts in Physics is a basic block without which you are nowhere.

Often when one understands that the theories thoroughly, we see that they can easily discover the relation between the quantities by which they can construct the formulas that generally derive it and learning for them will be simple.

The questions which are in the subject physics are something which challenges your skills and physics knowledge as well. These are grounded on three things:

  1. To examine what is provided and what is asked in the numerical.

  2. Next is the making use of the correct formula.

  3. Filling in the values and computing properly.

To crack all these kinds of challenges which are in the form of questions one needs to have a proper understanding of the subject of Physics formulae as well as its concepts.

Here,  provided all physics formulas in a simple format in our effort to create a repository where a scholar can get hold of any sought after formulas.


Important Physics Formulas

  • Planck constant h = 6.63 × 10−34 J.s = 4.136 × 10-15 eV.s

  • Gravitation constant G = 6.67×10−11 m3 kg−1 s−2

  • Boltzmann constant k = 1.38 × 10−23 J/K

  • Molar gas constant R = 8.314 J/(mol K)

  • Avogadro’s number NA = 6.023 × 1023 mol−1

  • Charge of electron e = 1.602 × 10−19 C

  • Permittivity of vacuum 0 = 8.85 × 10−12 F/m

  • Coulomb constant 1/4πε0 = 8.9875517923(14) × 109 N m2/C2

  • Faraday constant F = 96485 C/mol

  • Mass of electron me = 9.1 × 10−31 kg

  • Mass of proton mp = 1.6726 × 10−27 kg

  • Mass of neutron mn = 1.6749 × 10−27 kg

  • Stefan-Boltzmann constant σ = 5.67 × 10−8 W/(m2 K4)

  • Rydberg constant R = 1.097 × 107 m−1

  • Bohr magneton µB = 9.27 × 10−24 J/T 

  • Bohr radius a0 = 0.529 × 10−10

  • Standard atmosphere atm = 1.01325 × 105 Pa 

  • Wien displacement constant b = 2.9 × 10−3 m K .

  • Wave = ∆x ∆t wave = average velocity ∆x = displacement ∆t = elapsed time.

  • Vavg = (vi + vf*)2

Vavg = The average velocity 

vi = initial velocity 

vf = final velocity that is another definition of the average velocity which works where letter a is constant.

  • a = ∆v ∆t,

A = acceleration 

∆v = change in velocity 

∆t = elapsed time.

  • ∆x = vi∆t + 1/2 a(∆t)2

∆x = the displacement 

vi = the initial velocity 

∆t = the elapsed time 

a = the acceleration 

Use this formula when you don’t have vf. 

  • ∆x = vf∆t − 1/2 a(∆t)2

∆x = displacement 

vf = is the final velocity 

∆t = elapsed time 

a = acceleration 

Use this formula when you don’t have vi.

  • F = ma 

F = force 

m = mass 

Then a = acceleration Newton’s Second Law. 

F is the net force on the mass m. 

  • W = mg 

W = weight 

m = mass 

g = acceleration which is due to gravity.

Then we see that the weight of an object with mass m. This is said to be really just Newton’s Second Law. 

  • f = µN f = friction force 

µ = coefficient of friction 

N = normal force 

Here µ can be either the kinetic coefficient of friction µk or the static coefficient of friction. 

  • p = mv

  • W = F d cos θ or W = F!d 

W = work t

F = force 

d = distance 

θ = angle between F and the direction of motion 

  • KE  = 1/2 mv2 K

KE = kinetic energy

m = mass

v = velocity

  • PE = mgh 

PE = potential energy 

m = mass 

g = acceleration due to gravity 

h = height

  • W = ∆(KE) 

W = work done 

KE = kinetic energy. 

The “work-energy” which we have learnt is the theorem that is the work done by the net force on an object equals the change in kinetic energy of the object. 

We can write it as E = KE + PE 

E = total energy

KE = kinetic energy

PE = potential energy

  • P = W ∆t P = power

W = work

∆t = elapsed time

Power is the amount of work which is done per unit time that is power is the rate at which work is done.

FAQs on Physics Formulas

Q1. What is the Easiest way to Learn Physics Formulas?

Ans: The Tips memorize formulas in Physics:

  1. Scan through and familiarize. In Physics, we can see that there are variables which are repeated, for example, r or R is used for radius and it is common in most of the formulas as well.

  2. Apply and practice solving.

  3. Learn to derive formulas.

  4. Understand the structure and units of a formula.

  5. Next, take notes.

  6. Visualize and then test yourself.

Q2. What is the Formula of Distance in Physics?

Ans: To solve all problems for distance, use the formula for distance, d = st. The speed and the Rate are similar since they both represent some distance per unit time like miles per hour or kilometres per hour.

Q3. How I can Memorize Formulas Faster?

Ans: There are 7 Brain Hacks to learn and memorize things faster:

  1. We need to exercise to clear our head. Working out produces effects which is good for our bodies but our brain then reaps many benefits as well.

  2. Then next is to write down what needs to be memorized over and over.

  3. Practise meditation.

  4. Study or practice in the afternoon.

  5. Relate new things to what we already know.

  6. Stay away from multitasking.

  7. Teach other people what you've learned.
