Скачать или смотреть Find Error in K.E = p² / 2m | Short Trick for JEE NEET Physics

Welcome to SCC Simplify Physics by Shinde Sir

In this conceptual trick video, we solve a percentage error question based on Kinetic Energy using momentum:


---

📘 Formula Used:

K.E = \frac{p^2}{2m}


---

🧠 Error Propagation Rule:

\frac{\Delta K.E}{K.E} = 2 \cdot \frac{\Delta p}{p} + \frac{\Delta m}{m}


---

📐 Given Data:

Percentage error in momentum = 2%

Percentage error in mass = 1%



---

📊 Apply the Formula:

\frac{\Delta K.E}{K.E} = 2 \cdot 2 + 1 = \boxed{5\%}

✅ Final Answer: 5%
