Absolute Gravitational Potential Energy | Class 11 Physics Ch 5 | PE=mgh vs Absolute P.E.

Absolute Gravitational Potential Energy | Class 11 Physics Chapter 4 Gravitation In this lecture we will cover: 1. What is Absolute Gravitational P.E. ? 2. Why P.E. = 0 at infinity? 3. Why Absolute P.E. is always negative? 4. Difference between P.E. = mgh and Absolute P.E. = -GMm/r This lecture is for FSc 1st Year, Class 11, KPK Board, Federal Board, Punjab Board and MDCAT students. Formula: Absolute P.E = -GMm / r At infinity r = infinite, so P.E = 0 At earth surface, P.E is maximum negative. Watch full chapter 4 playlist for complete Gravitation.
