🧠 Core Ideas

  • Force → changes motion
  • Energy → conserved
  • Entropy → always increases
  • Fields → carry forces
  • Quantum → probabilistic
  • Relativity → space & time are flexible

📐 Essential Equations

Motion:

  • v=u+atv = u + atv=u+at
  • s=ut+12at2s = ut + \frac{1}{2}at^2s=ut+21​at2

Force:

  • F=maF = maF=ma

Energy:

  • KE=12mv2KE = \frac{1}{2}mv^2KE=21​mv2
  • PE=mghPE = mghPE=mgh

Momentum:

  • p=mvp = mvp=mv

Electricity:

  • V=IRV = IRV=IR

🌍 Fundamental Forces

  • Gravity
  • Electromagnetic
  • Strong nuclear
  • Weak nuclear

⚛️ Key Principles

  • Conservation of Energy
  • Conservation of momentum
  • Heisenberg Uncertainty Principle
  • Relativity of time

🔑 Mental Models (Very Important)

  • Think in systems, not objects
  • Always track energy flow
  • Use free-body diagrams
  • Approximate first, calculate later

📊 How to Study (High Efficiency Method)

  1. Learn concept (not formulas)
  2. Solve 10–20 problems
  3. Identify mistakes
  4. Re-learn weak areas
  5. Repeat

👉 Physics is not memorization — it’s pattern recognition.
