What are the most basic important formulas In physics?

In physics, to solve numericals you should know atleast some most basic important formulas which ease you to pick the concept-based questions asked to use formulas.

Here below some possible but not all physics formulas have been listed in simple pattern that will help you with some questions to have proper understanding of concepts in physics.

Most Basic Important Formulas in physics

1. What is the formula for speed?


2. Write the formula for distance in physics?

d = s*t (distance equals speed times time)

3. Formula for speed of a wave?

 v=Wavelength x Frequency.

4. T find Time Period

T = 2 π ω

5. period of a simple pendulum is T=2π√Lg

T = 2 π L g 

6. Ohms Law formula

V=IR where V is the potential difference, I is the Current passed through the conductor, R being Resistance that oppose the flow of the current passed into the conductor.

7. Newton’s law of gravitation formula

F=G (m1*m2)/r2

What are the 3 equations of motion?

Some Important Constant values in physics for some Physical quantities listed below

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

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

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

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

Mass of an electron me = 9.1 × 10-31 kg

Mass of proton = 1.672621923×10−27 kg

Mass of nuetron = 1.674927471×10−27 kg

Permittivity of free space  ε0 = 8.85418782 × 10-12 m-3 kg-1 s4 A2

speed of light = 3 ×108 m/s

This above formulas are taken from physics class 12 syllabus and made a formula sheet pdf for students to refer in their exams.
