- 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"
Jun 27, 2024 · Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
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).
Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.
The meaning of ACCELERATION is the act or process of moving faster or happening more quickly : the act or process of accelerating. How to use acceleration in a sentence.
Acceleration occurs anytime an object's speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous. Average acceleration is determined over a "long" time interval.
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 definition: 1. the increase in something's speed, or its ability to go faster: 2. the increase in the speed at…. Learn more.
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.

Dec 5, 2021 · Acceleration, denoted by the symbol a →, is a vector quantity defined as the rate of change of Velocity with respect to time. In calculus terms, it is the time derivative of the velocity vector. Acceleration indicates a change in the velocity vector's magnitude, direction, or both.
Acceleration is the change of velocity as time passes -- anytime we speed up or slow down, or change direction, we undergo acceleration. Let’s say we measure the velocity of the golf ball twice. Once just before we hit the ball, and once right after. We might get the following results: Velocity of golf ball before being hit: 0 meters / second (m/s)
