Memory Maps for IIT JEE Physics - Mental Map

Memory is map linking one concept to another concept. Mind map or mental map helps in your memorizing things.

Let me try to identify main concepts in each chapter and link them to more concepts related to each of them

Chapters from "Concepts of Physics Part I and II" by H C Verma


1. Introduction to physics

Physics - Understanding nature - Mathematics - Units - Dimensions

Units - Fundamental quantities - Derived quanties - SI units - SI Prefixes

SI Units - Metre - Kilogram - Second - Ampere - Kelvin - Mole

Dimension - Homogenuity - Conversion of Units

Understanding Nature - Structure of world

Order of magnitude

2. Physics and mathematics

3. Rest and motion :kinematics

Rest - Motion – displacement – Speed – Velocity – Acceleration – Frame of Reference

Displacement – Distance moved

Speed - average speed - instantaneous speed

Velocity - Average velocity - instantaneous velocity – Acceleration

Acceleration - Average acceleration - instantaneous acceleration

Motion - straight line - Motion in a plane - Projectile motion

Frame of Reference – Change in Frame of Reference

4. The forces

Forces - Gravitational forces - Electromagnetic (EM) forces - Nuclear Forces - Weak forces - Scope of Classical physics

Gravitational forces - G (universal constant 6.67 *106-11 N-m^2/kg^2) – Acceleration due to gravity g = GM/R^2) - Spherical body treated as a point mass at their centres

Electromagnetic (EM) forces – Coulomb forces – Forces between two surfaces in contact – Tension in a string or rope – Force due to a spring

Nuclear Forces – Exerted when interacting particles are protons or neutrons

Weak forces – Forces responsible for beta decay – antinutrino - positron

Scope of Classical physics – Applicable to bodies of linear sizes greater than 10^-6 m – Subatomic bodies – Quantum physics applicable – If the velocity of bodies are comparable to 3*10^* m/s relativistic mechanics is applicable.

5. Newtons law of motion

Newtons laws of motion - First law - second law - third law - Pseudo forces - Inertia

Newton's First law – Inertial frame of reference – Earth - Noninertial frame of reference

Newton's second law –( f = ma) - Freebody diagram

Newton's third law of motion – action - reaction

Pseudo forces – inertial forces

Inertia – a property which determines acceleration

6. Friction

Friction – Normal contact force – Friction - Kinetic friction - Static friction - Laws of friction - Atomic level friction – Rolling Friction

Kinetic friction – Opposite to motion – Coefficient of Kinetic friction –

Static friction - Limiting friction – Max. Static friction - Coefficient of static friction

Measurement of friction Coefficients- Horizontal table method – Inclined table method

7. Circular motion

Circular motion - Angular variables - Unit vectors along the radius and the tangent – Acceleration - Banking of roads in circular turns - Centrifugal force – Effects of earth's rotation

Angular variables – Angular position – Angular velocity – Angular acceleration – tangential acceleration

Unit vectors along the radius and the tangent – Tangential Unit vectors - Radial Unit vectors

Acceleration – Uniform circular motion - Nonuniform circular motion

Effects of earth's rotation – Colatitude – apparent weight

I am a retired HSC teacher and doing research in physics education for 35 years. Research in this field, spanning over 40 years, shows that circular motion is a very difficult topic for learning / teaching and hence related topics like the planetary motion / Bohr's model of H atom. WHY this is so? I started with this question in 1975 and arrived at something which can not be found in any existing textbook, Indian / foreign. As centenary of Bohr's model is in 2013, I request students/teachers to read my letter to the editor of CHANGE (Carnegie Foundation) May-June 2008, p. 5, You can send me sms also on 020-65100495 OR 09922467861
