Description
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:
- Work is force applied over a distance and is measured in Joules; no movement means no work is done.
- Energy is the capacity to do work, existing as potential (stored) or kinetic (motion), also measured in Joules.
- The Law of Conservation of Energy dictates that energy transforms between forms, like potential to kinetic, but is never lost.
- Power is the rate of doing work (Work/Time) and is measured in Watts, distinguishing it from the total work performed.
- Efficiency measures how effectively a machine converts work input into useful work output, always less than 100% due to energy loss.
