🧭 Classical Mechanics - Detailed Notes for Public Sector Exam

کلاسیکل مکینکس – تفصیلی نوٹس اردو + انگلش میں

📌 Overview / تعارف

Classical Mechanics is a branch of physics that deals with the motion of objects using concepts like force, mass, velocity, acceleration, energy, and momentum. It was developed primarily by Isaac Newton in the 17th century and remains the foundation of physics for most macroscopic systems.

کلاسیکل مکینکس فزکس کی وہ شاخ ہے جو اجسام کی حرکت کو قوت، کمیت، رفتار، توانائی، اور مومینٹم کے اصولوں کے ذریعے بیان کرتی ہے۔

🔑 Key Topics in Classical Mechanics | اہم موضوعات

1. Newton’s Laws of Motion | نیوٹن کے قوانین حرکت

2. Force and Inertia | قوت اور جمود

3. Work, Power, and Energy | کام، طاقت اور توانائی

4. Momentum and Impulse | مومینٹم اور جھٹکا

5. Circular Motion | دائرہ جاتی حرکت

6. Conservation Laws | بقائے قوانین

7. Lagrangian and Hamiltonian Mechanics (Intro)

8. Projectile Motion | گولی کی حرکت

9. Rotational Motion | گردش حرکت

⚖️ 1. Newton’s Laws of Motion (نیوٹن کے قوانین حرکت)

➤ First Law (Law of Inertia)

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Urdu: اگر کسی جسم پر بیرونی قوت نہ لگے تو وہ ساکن یا یکساں رفتار سے حرکت کرتا رہے گا۔

➤ Second Law (F = ma)

The force acting on an object is equal to the mass of the object multiplied by its acceleration.

F = ma

Urdu: قوت جسم کی کمیت اور اس کی عجلت کا حاصل ضرب ہے۔

➤ Third Law (Action-Reaction)

For every action, there is an equal and opposite reaction.

Urdu: ہر عمل کے برابر اور مخالف ردعمل ہوتا ہے۔

⚙️ 2. Force and Inertia

Force (قوت): Any push or pull on an object.

Inertia (جمود): The resistance of a body to change its motion.

⚡ 3. Work, Power & Energy

Work (کام): W = F × d × cosθ

Power (طاقت): P = Work / Time

Kinetic Energy: KE = (1/2)mv²

Potential Energy: PE = mgh

Total Mechanical Energy = KE + PE

Urdu Summary:

جب قوت کسی جسم پر لگائی جاتی ہے اور وہ فاصلہ طے کرتا ہے تو کام ہوتا ہے، توانائی کسی کام کی صلاحیت ہے۔

🚀 4. Momentum and Impulse

Momentum (مومینٹم): p = mv

Impulse: I = F × Δt = Δp

Law of Conservation of Momentum: In the absence of external forces, the total momentum of a system remains constant.

🔄 5. Circular Motion (دائرہ جاتی حرکت)

Centripetal Force: F = mv²/r

Angular Velocity (ω): ω = θ / t

Relationship: v = rω

Centripetal Acceleration: a = v²/r

🔁 6. Conservation Laws (بقائے قوانین)

Law of Conservation of Energy: Energy cannot be created or destroyed.

Law of Conservation of Momentum: Total momentum before = total momentum after

🎯 7. Projectile Motion (گولی کی حرکت)

A two-dimensional motion under gravity.

Horizontal velocity = constant

Vertical motion = under gravity (g = 9.8 m/s²)

Max height, time of flight, and range are important calculations.

🔄 8. Rotational Motion (گردشی حرکت)

Torque (ٹارک): τ = r × F

Moment of Inertia (I): Resistance to rotation.

Angular momentum (L): L = Iω

Rotational KE: KE = (1/2) Iω²

🧮 9. Important Formulas Summary

Concept Formula

Newton’s 2nd Law F = ma
Work W = F × d × cosθ
Power P = W / t
Kinetic Energy KE = (1/2)mv²
Potential Energy PE = mgh
Momentum p = mv
Impulse I = F × Δt = Δp
Centripetal Force F = mv² / r
Torque τ = r × F
Angular Velocity ω = θ / t
