Vehicle Performance — Lesson 2

This lesson covers the fundamental concepts of vehicle performance. It delves into the technical aspects of torque, power, speed, and energy, and how these factors influence a vehicle's movement. The lesson also explains the role of gears in multiplying torque and reducing speed, and the difference between normal and peak values for torque, speed, and power. It further discusses the impact of road conditions, traffic, and vehicle speed on power consumption. The lesson also introduces the concept of rolling resistance and aerodynamic resistance, and how these resistances can be overcome by applying torque or force.
