Important Physics Formulas for JEE Mains 2026
Many questions in JEE Mains are based directly on formulas. If students remember the most important formulas, solving numerical questions becomes faster.
Instead of memorising hundreds of equations, focus on high-frequency formulas that appear often in previous JEE exams. Below are some of the most useful formulas students should revise regularly.
Kinematics
Kinematics formulas describe motion without considering forces. These formulas are widely used in motion and projectile questions.
Important formulas include:
- Average velocity = Total displacement / Total time
- Velocity relation between distance and acceleration
- Displacement in uniformly accelerated motion
- Equation connecting velocity and displacement
- Relative velocity formula
Key formulas students should remember:
v=u+at
s=ut+1/2 at^2
v^2=u^2+2as
Relative velocity = v_AB=v_A-v_B
Projectile motion questions often combine these equations.
Work, Energy, and Power
Energy concepts appear frequently in JEE numerical problems. These formulas help solve questions related to motion and mechanical systems.
Important formulas include:
- Work done by a constant force
- Kinetic energy of a moving body
- Potential energy near Earth’s surface
- Power produced by a system
- Conservation of mechanical energy
Key formulas students should revise:
W=Fs cosθ
KE=1/2 mv^2
PE=mgh
Power (P) =Work/Time
Total Mechanical Energy = KE + PE
Many JEE problems require applying energy conservation instead of force equations.
Gravitation
Gravitation is an important part of Mechanics. Questions are often based on topics such as gravitational force, satellites, escape velocity, and gravitational potential energy.
Important formulas include:
- Universal law of gravitation
- Acceleration due to gravity
- Gravitational potential energy
- Orbital velocity
- Escape velocity
Key formulas include:
F = GMm/r^2
g = GM/R^2
U = -GMm/r
Orbital velocity vo=√(GM/r)
Escape velocity ve = √(2GM / R)
Satellite motion questions often use these formulas.
Electrostatics
Electrostatics is one of the most scoring topics in JEE Physics. Questions usually involve electric fields and forces.
Important formulas include:
- Coulomb’s force between two charges
- Electric field intensity
- Electric potential difference
- Electric potential energy
- Electric dipole moment
Key formulas include:
F = k (q₁q₂ / r²)
E = F/q
V=W/q
U = (𝑘𝑞1𝑞2) / 𝑟
Dipole moment p=q×d
Students should practise many field-based numerical problems.
Current Electricity
Current electricity formulas are simple but widely used in circuit-based questions.
Important formulas include:
- Ohm’s law relation
- Electric current definition
- Electrical power in a circuit
- Electrical energy consumption
- Drift velocity relation
Key formulas include:
V = IR
I = Q/t
P = VI
P = I2R
Electrical energy E = VIt
Circuit problems in JEE often combine series and parallel resistance concepts.
Waves and Optics
Optics formulas appear regularly in JEE Main. These formulas help solve ray diagrams and wave problems.
Important formulas include:
- Lens formula
- Mirror formula
- Magnification relation
- Wave speed relation
- Frequency relation
Key formulas include:
1/f = 1/v + 1/u
1/f = (μ − 1)(1/R₁ − 1/R₂)
v = fλ
n = c/v
Power of lens P = 1/f
SHM : x = A sin(ωt + φ)
Students should practise ray diagrams along with these formulas.
How to Revise Physics Formulas Quickly for JEE Mains
Physics revision becomes easier when students follow a simple system. Instead of memorising formulas randomly, use a structured method.
Create a Personal Formula Notebook
Write formulas chapter-wise in a small notebook. Keep only the most important formulas.
Revise Before Solving Questions
Always revise formulas before attempting practice problems.
Use Sticky Notes
Write tricky formulas on sticky notes and place them near the study desk.
Practice Numerical Problems
Formula memory improves when students solve more number of questions.
Revise Weekly
Spend 15 minutes every few days revising the entire formula sheet.
