Class 11 Physics: Chapter-Wise Formula Cheat Sheet for NEET & JEE
To crack high-level competitive exams like NEET and JEE Main, simply memorizing definitions isn't enough. You need complete mastery over the mathematical applications of Class 11 Physics. The image stack above contains 63 pages of neatly compiled formulas covering the entire syllabus. Below is a quick SEO-optimized overview of the chapters and some of the most complex, high-yield formulas you must know.
1. Kinematics & Laws of Motion
- Units & Measurements: Percentage error $\frac{\Delta x}{x}\times 100$.
- Projectile Motion: The equation of trajectory is highly tested: $y=x\tan\theta-\frac{gx^2}{2u^2\cos^2\theta}$.
- Banking of Roads (with friction): Maximum safe velocity is given by $v=\sqrt{Rg\frac{\mu_s+\tan\theta}{1-\mu_s\tan\theta}}$.
2. Work, Energy & Rotational Motion
- 1D Elastic Collision: Final velocity of mass 1 is $v_1=\frac{(m_1-m_2)u_1+2m_2u_2}{m_1+m_2}$.
- Parallel Axis Theorem: $I=I_{cm}+Md^2$.
- Rolling Motion: Total kinetic energy of a rolling body is $K=\frac{1}{2}mv^2(1+\frac{K^2}{R^2})$.
3. Properties of Matter & Gravitation
- Gravitation: Variation of $g$ with depth $d$ is $g_d=g(1-\frac{d}{R})$.
- Terminal Velocity (Viscosity): Dropping a sphere in a fluid: $v_t=\frac{2r^2(\rho-\sigma)g}{9\eta}$.
- Elasticity: Strain energy density is $U=\frac{1}{2}\times\text{stress}\times\text{strain}$.
4. Thermodynamics, Oscillations & Waves
- Carnot Engine: Maximum efficiency formula $\eta=1-\frac{T_2}{T_1}$.
- Physical Pendulum: Time period for a rigid body is $T=2\pi\sqrt{\frac{I}{mgd}}$.
- Doppler Effect (Sound): Apparent frequency when both source and observer move is $f'=f(\frac{v\pm v_o}{v\mp v_s})$.
Ensure you revise these mathematical relations daily. The formulas listed above represent the core difficulty of the Class 11 syllabus and are repeatedly asked in JEE Main and NEET physical mechanics sections.
