FE Exam Prep 24, Work-Energy Theorem and Conservation of Energy

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 Work-Energy Theorem states that the net work performed on an object is equal to its change in kinetic energy (W_net = ΔKE). - How to apply the full conservation of energy equation, including non-conservative forces like friction (KE₁ + PE₁ + W_other = KE₂ + PE₂). - Why defining a consistent zero-potential energy reference point, or datum, is a critical first step in solving energy problems. - That the work done by friction is always a negative value, as it removes energy from the system, and is calculated as W_friction = -μ_k * N * d. - On an inclined plane, the normal force (N) is a component of the object's weight, calculated as N = mgcos(θ), which is crucial for finding the friction force.
