Which statement about accelerating is true?

The statement that rough acceleration can cause mechanical damage is true because abrupt or aggressive acceleration places undue stress on a vehicle's components, particularly the transmission and drivetrain. When a driver accelerates too quickly, it can lead to increased wear and tear on the engine, transmission, and tires, as they struggle to handle the sudden increase in power and speed. This can result in mechanical issues over time, such as overheating, reduced efficiency, and even failure of parts.

Smooth and gradual acceleration is generally encouraged to extend the life of the vehicle and maintain optimal performance. It also enhances fuel efficiency, as rapid acceleration can lead to increased fuel consumption. Therefore, it is important for drivers to understand the significance of maintaining a smooth and controlled acceleration to both protect their vehicle and promote safe driving practices.
