Every formula you need for JEE Main & Advanced — tap any formula to practice it.

Kinematics

v = u + at

s = ut + \frac{1}{2}at^2

v^2 = u^2 + 2as

s_n = u + \frac{a(2n-1)}{2}

Laws of Motion

F = ma

f_s \leq \mu_s N

f_k = \mu_k N

Work Energy Power

W = Fs\cos\theta

KE = \frac{1}{2}mv^2

P = Fv\cos\theta

Rotational Motion

\tau = I\alpha

L = I\omega

KE = \frac{1}{2}I\omega^2

SHM

x = A\sin(\omega t + \phi)

T = 2\pi\sqrt{\frac{m}{k}}

T = 2\pi\sqrt{\frac{l}{g}}

Electrostatics

F = \frac{kq_1q_2}{r^2}

E = \frac{kq}{r^2}

V = \frac{kq}{r}

C = \frac{Q}{V}

Current Electricity

V = IR

P = VI = I^2R = \frac{V^2}{R}

R = \rho\frac{l}{A}

Magnetism

F = qvB\sin\theta

F = BIl\sin\theta

B = \frac{\mu_0 I}{2\pi r}

Modern Physics

E = hf

\lambda = \frac{h}{mv}

E = mc^2
