FSc 1st Year Physics new book |Chapter 4 Work, Energy and Power | Lecture 5 Energy & Kinetic Energy

Описание: Welcome to Science Teaching Zone 🎓 — your trusted platform for clear, concept-based learning!
In this video, we will discuss Lecture 5: Energy – Kinetic Energy from FSc 1st Year Physics (New Punjab Curriculum 2025), Chapter 4: Work, Energy, and Power.

🚗 Topic Overview:
In this lecture, we will explore the concept of kinetic energy — the energy possessed by a body due to its motion. You’ll understand how a moving car performs work against friction, and how that work is related to its ability to do work, i.e., kinetic energy.
We’ll derive the famous formula:

K.E. = \frac{1}{2}mv^2

✨ What you’ll learn in this lecture:

Definition and explanation of energy

Difference between potential and kinetic energy

Derivation of kinetic energy formula step-by-step

Real-life examples (like a moving car and rolling ball)

Units and dimensions of kinetic energy

Conceptual understanding with reasoning and visuals
