Energy Consumption per KM - I — Lesson 3

This lesson covers the fundamentals of vehicle dynamics and energy consumption. It delves into the forces applied to a moving vehicle, including aerodynamic resistance, rolling resistance, gradient resistance, and the force due to acceleration. The lesson also explains how these forces contribute to the total force required for a vehicle to accelerate and maintain a certain velocity. It introduces the concept of a drive cycle, which is a standard set of conditions used to measure a vehicle's performance. The lesson further discusses the power and energy requirements of different types of vehicles, such as two-wheelers, three-wheelers, four-wheelers, and small trucks. It also touches on the concept of regeneration, where deceleration or downhill travel can recover some energy.
