Laws of motion Topics - IIT JEE Syllabus

1

Force and inertia

2m1/10

📌 Key FormulaInertia: resistance to change in motion, Force causes acceleration.

2

Newton's First law of motion

2m1/10

📌 Key FormulaBody at rest or uniform motion unless acted upon by external force.

3

Momentum

2m1/10

📌 Key Formulap = mv

4

Newton’s Second Law of motion

2m2/10

📌 Key FormulaF = dp/dt = ma (if m constant)

5

Impulses

2m2/10

📌 Key FormulaJ = F dt = Δp

6

Newton’s Third Law of motion

2m1/10

📌 Key FormulaEvery action has equal and opposite reaction.

7

Law of conservation of linear momentum and its applications

2m3/10

📌 Key FormulaIf ΣF_ext = 0, then P = constant.

8

Equilibrium of concurrent forces

2m2/10

📌 Key FormulaΣF = 0

9

Static and Kinetic friction

2m2/10

📌 Key Formulaf_s ≤ μ_s N, f_k = μ_k N

10

Laws of friction

2m1/10

📌 Key FormulaFriction proportional to normal force, independent of area of contact.

11

Rolling friction

2m1/10

📌 Key FormulaMuch smaller than sliding friction.

12

Dynamics of uniform circular motion

2m2/10

📌 Key FormulaCentripetal force F = mv²/r

13

Centripetal force and its applications

2m4/10

📌 Key FormulaApplications: banking of roads, conical pendulum, etc.
