• Variable Force: Force changing with time/distance
• Impulse-Momentum: Collision and impact problems

📖 Sample Questions & Solutions

Question Type 1: Newton’s Second Law - Basic

Question (NEET 2023): A force of 50 N acts on a body of mass 10 kg. Find the acceleration produced.

Solution: Using Newton’s Second Law: F = ma Given: F = 50 N, m = 10 kg a = F/m = 50/10 = 5 m/s²

Key Concepts: Direct application of F=ma, unit consistency

Question Type 2: Connected Bodies

Question (NEET 2022): Two masses m₁ = 2 kg and m₂ = 3 kg are connected by a string passing over a smooth pulley. Find the acceleration of the system.

Solution:

• For m₁ (2 kg): T - 2g = 2a
• For m₂ (3 kg): 3g - T = 3a
• Adding: (3g - 2g) = 5a
• g = 5a
• a = g/5 = 9.8/5 = 1.96 m/s²

Key Concepts: Free body diagrams, system approach, simultaneous equations

🔄 Friction (45 Questions - 25%)

📋 Sub-topic Breakdown

🎯 Important Formulas

• Static Friction: fₛ ≤ μₛN (where μₛ is coefficient of static friction)
• Kinetic Friction: fₖ = μₖN (where μₖ is coefficient of kinetic friction)
• Angle of Repose: tan θ = μₛ
• Friction on Incline: Component analysis with normal force

📖 Sample Questions & Solutions

Question: Friction on Inclined Plane

Question (NEET 2024): A block of mass 5 kg rests on an inclined plane at 30°. If coefficient of static friction is 0.4, will the block slide?

Solution:

• Component of weight along plane: mg sin θ = 5 × 9.8 × sin 30° = 24.5 N
• Normal force: N = mg cos θ = 5 × 9.8 × cos 30° = 42.4 N
• Maximum static friction: fₘₐₓ = μₛN = 0.4 × 42.4 = 16.96 N
• Since 24.5 N > 16.96 N, the block will slide

Key Concepts: Force components, friction comparison, equilibrium condition

📖 Practice Friction Questions

🌀 Circular Motion (40 Questions - 22%)

📋 Sub-topic Breakdown

🎯 Key Formulas

• Centripetal Force: F = mv²/r
• Centripetal Acceleration: a = v²/r = ω²r
• Banking Angle: tan θ = v²/rg (for frictionless banking)
• Critical Speed: v = √(rg tan θ)

📖 Sample Questions & Solutions

Question: Circular Motion with String

Question (NEET 2023): A stone of mass 0.5 kg is tied to a string of length 1 m and rotated in a vertical circle. Find the minimum speed at the top point.

Solution: At the top point, both tension and weight provide centripetal force: T + mg = mv²/r For minimum speed, T = 0: mg = mv²/r v² = gr = 9.8 × 1 = 9.8 v = √9.8 = 3.13 m/s

Key Concepts: Critical speed condition, force analysis in circular motion

Question: Pulley System with Acceleration

Question (NEET 2022): In the arrangement shown, if the system is released from rest, find the acceleration of 5 kg block.

Solution:

• For 5 kg block: 5g - T = 5a
• For 2 kg block: T - 2g = 2a
• Adding: 3g = 7a
• a = 3g/7 = 3×9.8/7 = 4.2 m/s²
