What is the difference between low gear and high gear?

[CassidyRose]

The difference between high gear and low gear in a car lies in whether a large gear drives a small gear or vice versa. First gear has slow rotational speed but high torque, making it suitable for climbing hills or hauling heavy loads, which typically require low gears. In contrast, fifth gear has lower torque but higher speed, making it ideal for highway driving. Below is a detailed introduction to car gears: 1. First gear: Used for normal starts or climbing very steep hills. The speed is generally around 10 km/h. 2. Second gear: A transitional gear for acceleration after starting or for low-speed driving, with speeds generally around 20 km/h. 3. Third gear: Used at speeds between 20-40 km/h, commonly used for city driving. 4. Fourth gear: Used at speeds between 40-60 km/h. 5. Fifth gear: Used at speeds above 60 km/h.
