Acceleration

the rate at which a vehicle increases its speed over a specific distance or time

What is "acceleration"?

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.

Examples
The driver 's car showed impressive acceleration coming out of the corner.
02

an increase in the rate of change of something

03

(physics) the increase in velocity over time
