Got you, Ashutosh 👍 — here are SSC ke liye super-short shortcut notes for Units & Dimensions (revision-friendly):🔹 1. Basic ConceptPhysical Quantity = Numerical value + UnitExample: 5 m, 10 kg🔹 2. Fundamental (Base) Quantities (Yaad trick: MLT KAT)QuantityUnitSymbolLengthmetermMasskilogramkgTimesecondsTemperaturekelvinKCurrentampereA🔹 3. Derived Quantities (Most Important for SSC)Velocity = m/s → [LT⁻¹]Acceleration = m/s² → [LT⁻²]Force = kg·m/s² → [MLT⁻²]Work/Energy = Force × distance → [ML²T⁻²]Power = Work/time → [ML²T⁻³]Pressure = Force/Area → [ML⁻¹T⁻²]Density = Mass/Volume → [ML⁻³]👉 Shortcut yaad trick:Force → MLT⁻²Energy → Force × L → ML²T⁻²Power → Energy / T → ML²T⁻³🔹 4. Important Dimensionless Quantities (SSC favourite)(No unit, no dimension)StrainRefractive IndexRelative DensityAngle🔹 5. Use of Dimensional FormulaFormula check karnaUnit convert karnaRelation find karna🔹 6. Important Unit Conversions (Rapid Fire)1 km = 1000 m1 hour = 3600 s1 N = 1 kg·m/s²1 J = 1 N·m1 W = 1 J/s🔹 7. Exam Hacks (Very Important ⚡)Dimensions me constant ignore karoAddition/subtraction me same dimension hona chahiyeTrigonometric, log → dimensionless input🔹 8. Most Repeated Question Pattern“Find dimension of X”“Which is dimensionally correct?”“Find relation between quantities”🔹 Ultra Shortcut Revision (30 sec me)Force → MLT⁻²Energy → ML²T⁻²Power → ML²T⁻³Pressure → ML⁻¹T⁻²Density → ML⁻³
