Few Important JEE Main Physics Formulas 2026

Aspirants preparing for JEE Mains must remember that, along with concepts, one needs to revise and remember the formulas, which are very important while solving any problems. As JEE Main Physics formulas are given below, these formulas need to be memorised daily, as direct questions and formulas are asked in exams. Students can also solve JEE Main Chapter-Wise PYQs.

Below are a few important formulas for JEE Main Physics.

Formulas for Kinematics

1. Average speed = Total distance/Total time

2. Average velocity = Total displacement/Total time

3. Acceleration $=($ Final velocity - Initial velocity $)/$ Time taken

Newton's Law of Motion

1. $F=m\times a$ (Newton's Second Law of Motion)

2. Impulse $=$ force $\times$ time

Formulas for Work, Energy, and Power:

1. Work $=$ force $\times$ displacement $\times \cos \theta$

2. Kinetic Energy $=0.5\times m\times v^2$

3. Potential Energy $=m\times g\times h$

4. Total Mechanical Energy = Kinetic Energy + Potential Energy

5. Power $=$ work done/time taken

Electric Charge and Fields Formulas:

1. Electric Field $=$ force per unit charge $=\frac{F}{Q}$

2. Coulomb's Law: $F=\frac{k\times (q_1\times q_2)}{r^2}$

3. Energy of electric dipole: $U=-\rho E$

4. Energy of a magnetic dipole: $U=-\mu BC$

5. Electric Charge: $Q=\pm ne$

6. Electrostatic Force $(\mathrm{F})=k\left[\frac{q_1{q}_2}{r_2}\right]$

7. The current at Time $t:i=\underset{\mathrm{\Delta }t\to 0}{lim}\frac{\mathrm{\Delta }Q}{\mathrm{\Delta }t}=\frac{dQ}{dT}$

8. Law of Conservation of Charge: $I_3=I_1+I_2$

9. Resistivity : $\rho (T)=\rho \left(T_0\right)[1+\alpha (T-T_0)]$

10. Lorentz Force : $\overrightarrow{F}=q[\overrightarrow{E}+(\overrightarrow{v}\times \overrightarrow{B})]$

11. Magnetic Flux through Area $dS=\phi =\overrightarrow{B}\cdot d\overrightarrow{S}=B\cdot dS\cos \theta$

Projectile Equation of Motion:

1. Horizontal Range $(R)=\frac{u^2\sin 2\theta }{g}$

2. Time of Flight $(T)=\frac{2u\sin \theta }{g}$

3. Maximum Height $(H)=\frac{u^2\sin 2\theta }{2}$

Laws of Gravity

1. Gravitational force $\overrightarrow{F}=G{\left[\frac{Mm}{r^2}\right]}^r$

2. Work Done by Constant Force: $W=\overrightarrow{F}\cdot \overrightarrow{S}=|\overrightarrow{F}||\overrightarrow{S}|\cos \theta$

3. Simple Harmonic Motion: Force $(F)=-kx$ and $k={\omega }^{2}m$

4. Torque: $M=r\times F$

Preparation tips for JEE Mains

Given below are some tips to help you prepare for JEE Main and score good marks in the exam:

1. First, students need to understand the Syllabus and Exam Pattern so that they can refer to the JEE Main syllabus from the official website.

2. Try to identify the important and high-weightage topics and prepare according to that.

3. Create an effective study plan according to your preparation level. Divide your preparation into monthly, weekly, and daily targets and allocate more time to difficult subjects or topics.

4. Students must focus on conceptual clarity; they must understand the logic and derivations behind every formula.

5. Try to solve questions regularly. Solve previous years' JEE Main question papers and attempt mock tests and sample papers regularly.

Tips to Learn Physics Formulas for JEE Main 2026

Students find it difficult to learn formulas for JEE Main, but with the right approach, they can remember. Given below are some points to remember:

1. Students must try to understand why a formula works. For example, derivations in Physics or Maths often follow a logical pattern.

2. Then break down formulas into chapters or topics.

3. To learn these formulas easily, try to make a formula notebook.

4. Sometimes students must try to make Mnemonics and short tricks, as it helps in quick revision.

5. Try to solve as many questions and revise

6. Try to use diagrams and flowcharts.
