NIOS Class 12 Physics — Formula Sheet

NIOS Class 12 Physics formula sheet, chapter by chapter — 432 formulas across 30 chapters. Follows the NIOS syllabus.

How to Use the Formula Sheet

  1. Write, don't just read — writing each formula out helps it stick.
  2. Understand the derivation — you can rebuild a formula you half-remember.
  3. Group related formulas — link the ones that build on each other.
  4. Test yourself — cover the sheet and write the formulas from memory.

1

Units, Dimensions and Vectors

6 entries
[M L T] represents dimensions
Dimensional Equation Checking: Check if both sides have same dimensions
Deriving Physical Relations: If x ∝ aᵐ·bⁿ, then equate dimensions and solve for m and n
Unit Conversion: Multiply by conversion factor (dimension preservation)
1 metre = distance light travels in vacuum in 1/299,792,458 seconds

2

Motion in a Straight Line

16 entries
Average Velocity (v̄) = Δx / Δt = (x₂ - x₁) / (t₂ - t₁)
Average Speed = Total Distance Travelled / Total Time Taken
Relative Velocity of B w.r.t. A: v_BA = v_B - v_A
Average Acceleration (ā) = Δv / Δt = (v₂ - v₁) / (t₂ - t₁)
Instantaneous Velocity: v = lim(Δt→0) (Δx/Δt) = dx/dt

3

Laws of Motion

13 entries
p = mv
F = ma
F = Δp / Δt
Impulse J = F·Δt = Δp = mv − mu
F₁₂ = −F₂₁
