Описание: 📘 1st Year Physics – New Book (PCTB 2025)
🎥 Topic 5.14 – Terminal Velocity
#physicsofhow

In this video, we discuss *Terminal Velocity* from *Chapter 5 – Solids and Fluids* of the new 1st Year Physics book (PCTB 2025). Understand how a falling object reaches a constant speed when the downward and upward forces balance each other.

🔍 What You Will Learn:
✅ What is Terminal Velocity?
✅ Explanation using forces: weight, upthrust, and viscous drag
✅ Derivation of terminal velocity using *Stokes’ Law*
✅ Factors affecting terminal velocity (radius, density, viscosity)
✅ Examples: raindrops, oil droplets, and parachutes

🎓 Perfect for:
– 1st Year / 11th Class Physics Students
– Punjab Board (PCTB 2025)
– Urdu & English Medium Learners

📌 Chapter: 5 – Solids & Fluids
📌 Topic: 5.14 – Terminal Velocity
