Explore the work-energy theorem stating that net work done on an object equals its change in kinetic energy (Wnet = ΔKE). Understand that work is force times displacement in the direction of force (W = Fd cos θ), measured in joules. Visualize how positive work increases kinetic energy, negative work decreases it, and perpendicular forces do zero work. Apply the theorem to analyze motion with varying forces, friction, and gravitational effects.
