1
加速, 速度增加
the rate at which a vehicle increases its speed over a specific distance or time
Acceleration is the rate at which a vehicle's speed increases over time. It refers to how quickly a car, truck, or motorcycle can increase its speed from a standstill or low speed to a higher one. The faster the vehicle reaches its desired speed, the higher its acceleration. This is usually measured in meters per second squared (m/s²). A vehicle's acceleration depends on factors like engine power, weight, and aerodynamics. High-performance cars, for instance, can have very fast acceleration, allowing them to go from 0 to 60 miles per hour in just a few seconds.
