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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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

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.

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

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.

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.
