This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The core work-energy equation is T1 + V1 + U_non-conservative = T2 + V2. - Non-conservative work (U) accounts for energy added or removed by external forces like friction or motors. - Potential energy for a spring (V = 1/2 * k * s^2) uses displacement 's' from its *unstretched* length, a common exam trap. - The work done by friction is always negative as it opposes the direction of motion, representing an energy loss. - Power is the time rate of doing work (P = F*v or T*ω), and efficiency is always Power Out / Power In.
