In physics, to solve numerical you should know at least 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 patterns that will help you with some questions to have a proper understanding of concepts in physics.

## Most Basic Important Formulas in Physics

1. What is the formula for speed?

speed=distance/time

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 Ï€ Ï‰

5. **period** of a **simple pendulum** is T=2Ï€âˆšLg

T = 2 Ï€ 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)/r^{2}

What are the 3 equations of motion?

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

Gravitation constant G = 6.67Ã—10^{âˆ’11} m^{3} kg^{âˆ’1} s^{âˆ’2}

Planck constant h = 6.63 Ã— 10^{âˆ’34} J.s = 4.136 Ã— 10^{-15} eV.s.

Boltzmann constant k = 1.38 Ã— 10^{âˆ’23} J/K.

Charge of electron e = 1.602 Ã— 10^{âˆ’19} C.

Mass of an electron m_{e} = 9.1 Ã— 10^{-31} kg

Mass of proton = 1.672621923Ã—10^{âˆ’27} kg

Mass of nuetron = 1.674927471Ã—10^{âˆ’27} kg

Permittivity of free space **Îµ _{0}** = 8.85418782 Ã— 10

^{-12}m

^{-3}kg

^{-1}s

^{4}A

^{2}

speed of light = 3 Ã—10^{8} 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.
