noun
- 1. a vehicle's capacity to gain speed within a short time: "a Formula One car is superior to an Indy car in its acceleration"
1. a. : the act or process of moving faster or happening more quickly : the act or process of accelerating. rapid acceleration. the acceleration of economic growth. b. : ability to accelerate. a car with good acceleration. 2. physics : the rate of change of velocity with respect to time. broadly : change of velocity.
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Acceleration is one of several components of kinematics, the study of motion. Accelerations are vector quantities (in that they have magnitude and direction ).
definition. When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. In everyday English, the word acceleration is often used to describe a state of increasing speed.
the increase in something's speed, or its ability to go faster: An older car will have poor acceleration. High winds significantly hampered the plane's acceleration. [ S or U ] the increase in the speed at which something happens: The acceleration in the decline of manufacturing industry began several years ago.

An increase in the magnitude of the velocity of a moving body (an increase in speed) is called a positive acceleration; a decrease in speed is called a negative acceleration. Acceleration, like velocity, is a vector quantity, so any change in the direction of a moving body is also an acceleration.
About. Transcript. Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction. Created by Sal Khan.
