- 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.
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.
Feb 20, 2022 · In everyday conversation, to accelerate means to speed up. The accelerator in a car can in fact cause it to speed up. The greater the acceleration, the greater the change in velocity over a given time.
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.
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.

Average acceleration is acceleration at a given point in time; instantaneous acceleration is the change in displacement divided by the elapsed time. Average acceleration is the change in velocity divided by the elapsed time; instantaneous acceleration is acceleration at a given point in time.
