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).
In fisica, in primo luogo in cinematica, l'accelerazione è una grandezza vettoriale che rappresenta la variazione della velocità nell'unità di tempo. In termini differenziali, è pari alla derivata rispetto al tempo del vettore velocità. Nel SI l'unità di misura del modulo dell'accelerazione è il m/s², ovvero metro al secondo quadrato ...
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 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.
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.
Define and distinguish between velocity and acceleration, and between instantaneous and average acceleration. Calculate acceleration given initial time, initial velocity, final time, and final velocity.
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.
