WBBSE Madhyamik Physical Science study guide
WBBSE Madhyamik Physical Science · Work through your exam, one topic at a time.
Madhyamik Physical Science is the Class X science paper of the West Bengal Board of Secondary Education (WBBSE) Madhyamik Pariksha, the first public board examination most students in the state sit. It is a single subject combining physics and chemistry: measurement and motion, force, work and energy, heat, sound, light, electricity and electromagnetism, plus matter and gas laws, atomic structure and bonding, metals, non-metals, electrolysis and organic chemistry. The WBBSE Madhyamik Physical Science study guide has 9 sections and about 2,883 words.
01Measurement and Motion
Measurement and Motion is the foundation domain of the Madhyamik Physical Science paper: it checks whether you can choose SI units, read laboratory instruments correctly and describe motion with equations and graphs rather than vague words. SI base units used here are metre (length), kilogram (mass) and second (time); derived units include newton (force), joule (work) and watt (power).
309 words, about 2 min02Force, Work and Energy
Force, Work and Energy tests Newton's laws, momentum conservation and the work-energy relation. Numerical questions usually combine a force diagram with an energy calculation, so keep the direction of force and displacement clear.
333 words, about 2 min03Heat and Thermal Phenomena
Heat and Thermal Phenomena covers thermal expansion, calorimetry and the three modes of heat transfer. The exam expects correct temperature intervals, correct units and a clear distinction between heat and temperature.
340 words, about 2 min04Sound and Waves
Sound and Waves tests wave terminology, the conditions for sound propagation and echo calculations. The key is to separate frequency, amplitude and speed and to use the echo distance correctly.
333 words, about 2 min05Light: Reflection and Refraction
Light: Reflection and Refraction examines mirror and lens formulae, sign conventions and refractive index. Most lost marks come from signs, not from algebra.
333 words, about 2 min06Electricity and Electromagnetism
Electricity and Electromagnetism tests Ohm's law, resistor networks, electric power and the magnetic effect of current. Expect numericals on series and parallel circuits plus qualitative questions on electromagnets and induction.
329 words, about 2 min07Matter, Gas Laws and Chemical Calculations
Matter, Gas Laws and Chemical Calculations links kinetic theory, the gas laws and mole-based stoichiometry. The exam tests whether you can convert mass to moles and then to particles or gas volume.
278 words, about 1 min08Atomic Structure, Periodic Table and Chemical Bonding
Atomic Structure, Periodic Table and Chemical Bonding asks you to connect subatomic particles to electron arrangement, then to position in the periodic table and to the type of bond formed. An atom has protons and neutrons in the nucleus and electrons in shells around it.
314 words, about 2 min09Metals, Non-metals, Electrolysis and Organic Chemistry
Metals, Non-metals, Electrolysis and Organic Chemistry combines reactivity, electrochemical cells and the first rules of carbon chemistry. Questions often ask you to predict a displacement reaction, identify electrode products or name a hydrocarbon.
