acceleration
n 1: an increase in rate of change; "modern science caused an
acceleration of cultural change" [ant: {deceleration},
{retardation}, {slowing}]
2: the act of accelerating; increasing the speed [synonym:
{acceleration}, {quickening}, {speedup}] [ant:
{deceleration}]
3: (physics) a rate of increase of velocity [ant:
{deceleration}]

Acceleration \Ac*cel`er*a"tion\, n. [L. acceleratio: cf. F.
acc['e]l['e]ration.]
The act of accelerating, or the state of being accelerated;
increase of motion or action; as, a falling body moves toward
the earth with an acceleration of velocity; -- opposed to
{retardation}.
[1913 Webster]

A period of social improvement, or of intellectual
advancement, contains within itself a principle of
acceleration. --I. Taylor.
[1913 Webster] (Astr. & Physics.)

{Acceleration of the moon}, the increase of the moon's mean
motion in its orbit, in consequence of which its period of
revolution is now shorter than in ancient times.

{Acceleration} and {retardation of the tides}. See {Priming
of the tides}, under {Priming}.

{Diurnal acceleration of the fixed stars}, the amount by
which their apparent diurnal motion exceeds that of the
sun, in consequence of which they daily come to the
meridian of any place about three minutes fifty-six
seconds of solar time earlier than on the day preceding.


{Acceleration of the planets}, the increasing velocity of
their motion, in proceeding from the apogee to the perigee
of their orbits.
[1913 Webster]

  • Acceleration - Wikipedia
    Acceleration is the rate of change of velocity At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction at that point The true acceleration at time t is found in the limit as time interval Δt → 0 of Δv Δt
  • Acceleration: Definition, Formula, and Solved Problems
    What is acceleration How to find its magnitude Does it have a direction Learn its equations units, along with graphs Also, learn linear tangential acceleration
  • Acceleration | Definition, Facts, Units | Britannica
    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
  • Acceleration - The Physics Classroom
    Acceleration is the rate at which they change their velocity Acceleration is a vector quantity; that is, it has a direction associated with it The direction of the acceleration depends upon which direction the object is moving and whether it is speeding up or slowing down
  • 2. 4: Acceleration - Physics LibreTexts
    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 formal definition of acceleration is consistent with these notions, but more inclusive
  • Acceleration - Physics Book
    The acceleration is the slope of the velocity graph; a positive acceleration means the velocity is increasing and should have a positive slope, and a negative acceleration means the velocity is decreasing and has a negative slope
  • How to Calculate Acceleration: The 3 Formulas You Need
    Acceleration is the amount by which the velocity of something changes over a set period of time In this article, we’ll be talking all about acceleration: what it is and how to calculate it
  • Acceleration Calculator | Definition | Formula
    Acceleration is the rate of change of an object's speed; in other words, it's how fast velocity changes According to Newton's second law, acceleration is directly proportional to the summation of all forces that act on an object and inversely proportional to its mass
  • Homepage - Acceleration Academies
    Here, students focus on one course at a time instead of juggling many They build strong relationships with mentors and teachers They choose their own schedule so school fits around their real life The result? Students who once felt stuck start building confidence, enjoying school again, and making progress toward their diploma Stay on Track
  • 3. 1 Acceleration - Physics | OpenStax
    Average acceleration is distinguished from instantaneous acceleration, which is acceleration at a specific instant in time The magnitude of acceleration is often not constant over time
