• Writing and Composition: Skills for effective communication.
  • Importance of clarity and coherence.
  • Different forms of writing (essays, stories, letters).

Classical Mechanics

• Newton's three laws of motion govern the relationship between a body and the forces acting upon it, and its motion in response to those forces.
• Energy, the capacity to do work, exists in various forms (kinetic, potential, etc.) and is conserved in closed systems.
• Momentum, a measure of mass in motion, is also conserved in the absence of external forces.

Thermodynamics

• The First Law of Thermodynamics states that energy cannot be created or destroyed, only transformed.
• The Second Law of Thermodynamics describes the increase of entropy (disorder) and irreversibility in natural processes.
• Enthalpy represents the total heat content of a system at constant pressure.

Electromagnetism

• Maxwell's equations unify electricity and magnetism, describing their interactions and the propagation of electromagnetic waves.
• Voltage is the electrical potential difference between two points. Current is the flow of electric charge. Resistance opposes the flow of current.

Quantum Mechanics

• Wave-particle duality describes the ability of matter to exhibit properties of both waves and particles.
• The Heisenberg Uncertainty Principle states that it is impossible to simultaneously know both the position and momentum of a particle with perfect accuracy.

Atomic Structure

• Atoms consist of protons (positive charge), neutrons (neutral charge), and electrons (negative charge).
• Atomic number represents the number of protons, defining an element's identity. Mass number is the sum of protons and neutrons.

Chemical Bonding

• Ionic bonds result from the electrostatic attraction between oppositely charged ions.
• Covalent bonds involve the sharing of electrons between atoms.
• Metallic bonds arise from the delocalized electrons in a metal lattice.

Stoichiometry

• Balanced chemical equations represent the quantitative relationships between reactants and products.
• Molar mass is the mass of one mole (6.022 x 10²³) of a substance.

Thermochemistry

• Exothermic reactions release heat to their surroundings, while endothermic reactions absorb heat.
• Calorimetry techniques measure the heat changes in chemical reactions.

Cell Biology

• Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells possess both.
• Organelles like mitochondria (energy production) and the endoplasmic reticulum (protein synthesis) perform specialized functions.

Genetics

• Mendelian genetics explains inheritance patterns based on the segregation and independent assortment of genes.
• DNA’s double helix structure carries the genetic code, directing protein synthesis and inheritable traits.

Evolution

• Natural selection favors individuals with advantageous traits, leading to adaptation and speciation.
• Fossil records, comparative anatomy, and molecular biology provide evidence for evolution.

Ecology

• Ecosystems consist of all living organisms (biotic factors) and their physical environment (abiotic factors) in a specific area.
• Food webs illustrate the complex feeding relationships within ecosystems.

Grammar (English & Hindi)

• English and Hindi grammars both utilize nouns, verbs, adjectives, etc., but their structures and rules differ significantly. Both languages have various sentence structures.

Literature (English & Hindi)

• Both English and Hindi literature encompass diverse genres (fiction, poetry, drama) and literary devices (metaphor, symbolism).
• Knowledge of significant authors and works is crucial for understanding literary movements and cultural contexts in both languages.

Writing Skills (English & Hindi)

• Effective writing in both languages necessitates clarity, coherence, and appropriate structure (e.g., essay format).
• Different writing forms (essays, stories, letters) require specific approaches and stylistic choices.
