These 12 science formulas will help you throughout your scientific journey.

When it comes to the examination, it can be nerve-wracking to go through everything in a day. Science can be intimidating for students. They tend to run away from the subject cause they don’t know how to prepare for it.

For that, you tend to grasp these all-time science formulas, which will help you throughout your studies. If you ever felt the need for the complete ** physics formulas** list, you can also check them out and jot them down for reference.

Sometimes science can be a bit overwhelming, so you need to find the best preparation strategy that will help you in your board examinations and competitive examinations.

**Here are some of the best science formulas that will help you ace your exam.**

**1. Newton’s Law**

In this law, there’re three statements describing the relationship between the motion of an object and the force acting on the object.

**The First Law of Motion-** Also known as the law of inertia, states, “An object remains at rest or in uniform motion in a straight line until and unless an external force acts upon it.”

**Second Law of Motion-** The law states that “the force is equal to the rate of change of momentum.” It shows that the momentum of an object is equal to both the momentum and direction of force implied on the object.

**Formula-** Force= Mass x Acceleration

**The third Law of Motion- **Also known as the law of action or reaction, states, “When two bodies interact, and they apply forces towards each other that are equal in magnitude but in the opposite direction.”

**Formula- ** F_{AB} = F_{BA}

**2. Gauss Law**

The law states that “ the intotal flux connected with the closed surface is 1/ε0 times the charge of the closed surface.”

**Formula-** ϕ = Q/ϵ0

Where Q is the total charge within the closed surface

and ϵ0 is the electric constant

**3. Kepler’s Law**

This law also has three statements representing a planet’s motion around the sun.

The first law, also known as the law of orbits, states, “All the planets revolve around the sun in the elliptical orbit at one of the foci.”

**Formula-** e = √ 1- (b/a)^{2}

**The second law- **Also known as the law of equal areas, states, “ The radius vector to the planet drawn from the sun sweeps out all the equal areas in an equal interval of time.”

**Formula-** dA/dt = L/2m

where, dA/dt = constant

**The third law-** Also known as the law of the period, states, “ The square of the time of the revolution of the planet around the sun in an elliptical orbit is directly proportional to the cube of the semi-major axis.”

**Formula-** P^{2} = 4π^{2} /[G(M_{1}+ M_{2})] × a^{3}

**4. Kinetic**

Also represented as KE, defines that the kinetic energy of an object is the measure of the work that can be done by the virtue of its motion.

**Formula- **KE = ½ mv^{2}

where m represents the body’s mass

and v represents the body’s velocity

**5. Raoult’s Law**

Named after the french chemist François-Marie Raoult, this law states, “ The partial vapour pressure of the solvent is is equal to the product of the vapour pressure of the pure solvent and the mole fraction in the solution.”

**Formula-** P_{solution} = Χ_{solvent }* P0_{solvent}

where P_{solution} is the vapour pressure of the solution,

Χ_{solvent } is the mole fraction,

and P0_{solvent} is the vapour pressure of the pure solvent

**6. Molarity**

It is defined as the total number of moles of solute per liter of solution

**Formula-** M = n/V

where M is the molarity of the solution

n is the number of moles of the solute

and V is the volume of the solution

**7. Specific Resistivity**

Defined as the resistance offered per unit length and the unit cross-sectional area when a specific amount of voltage is applied to it.

**Formula-** ⍴ = RA/L

where ⍴ is the specific resistance,

R is the resistance,

A is the cross-sectional area,

and L is the length of the material

**8. Avogadro Law**

The law states, “ The total number of atoms of gas is directly proportional to the volume applied by the gas at a specific temperature and pressure.”

**Formula-** k = V/n

where V is the volume of the gas,

k is the constant,

and n is the amount of the gaseous substances

**9. Current Formula**

The continuous flow of electrons in an electric circuit is called electric current.

**Formula- ** I= V/R

where I is the electric current,

V is the voltage,

and R is the resistance

**10. Henry’s Law**

It is known as the gas law, which states that “ the total amount of gas which is dissolved in the liquid is directly proportional to the partial pressure of the gas above the liquid when the temperature is constant.”

**Formula-** P = k_{H} x C

where P is the partial pressure of the gas,

k_{H} is Henry’s law constant of the gas

and C is the concentration of the dissolved gas

**11. Nernst Equation**

This equation defines the calculation of the cell potential of an electrochemical cell, potential, temperature, the standard cell, and the reaction quotient.”

**Formula-** E_{cell} = E^{0} – [RT/nF] ln Q

where E_{cell} is the cell potential

E^{0} is the cell potential under standard cell

R is the universal gas constant

T is the temperature

n is the number of electrons transferred

F is the Faraday constant

and Q is the reaction quotient

**12. Kirchhoff’s Law**

There are two laws under Kirchhoff’s law that deal with the current and energy with the current analysis.

**First law-** This law states that “the total amount of current entering a junction equals the charge leaving the junction as no charge is lost.”

**Formula-** I_{1} + I_{2} + I_{3} – I_{4} – I_{5} = 0

**Second law-** The second states that “the voltage around the loop adds the sum of all the voltage drops and results in zero.”

**Formula-** V_{1} + V_{2} + (-V_{3}) + (-V_{4}) = 0

**Summary**

This is a detailed list of the best 12 science formulas to help you with your studies. We often heard students having problems with their preparation during examinations and forgetting the crucial formulas which are necessary for every class.
