1. accelerationnoun

   The act of accelerating, or the state of being accelerated; increase of motion or action; as opposed to retardation or deceleration.

   a falling body moves toward the earth with an acceleration of velocity

2. accelerationnoun

   The amount by which a speed or velocity increases (and so a scalar quantity or a vector quantity).

   The boosters produce an acceleration of 20 metres per second per second.

3. accelerationnoun

   The change of velocity with respect to time (can include deceleration or changing direction).

4. Etymology: * First attested in 1531.

1. Accelerationnoun

   Etymology: acceleratio, Lat.

   1. The act of quickening motion.

   The law of the acceleration of falling bodies, discovered first by Galileo, is, that the velocities acquired by falling, being as the time in which the body falls, the spaces through which it passes, will be as the squares of the velocities, and the velocity and time taken together, as in a quadruplicate ratio of the spaces.

   2. The state of the body accelerated, or quickened in its motion.

   The degrees of acceleration of motion, the gravitation of the air, the existence or non-existence of empty spaces, either coacervate or interspersed, and many the like, have taken up the thoughts and times of men in disputes concerning them. Matthew Hale, Origin of Mankind.

1. acceleration

   Acceleration is the rate of change of velocity per unit of time. In physics, it is a vector quantity with both magnitude and direction. It's measured in meters per second squared (m/s²). Positive acceleration means an increase in velocity over time, while negative acceleration or deceleration represents a decrease in velocity over time.

2. acceleration

   Acceleration is a physical concept that describes the rate of change of velocity of an object over time. It is a vector quantity, meaning it has both a magnitude (speed) and direction. Positive acceleration means an increase in velocity, while negative acceleration, also known as deceleration, indicates a decrease in velocity. It is measured in units of distance per time squared (typically, meters per second per second, or m/s^2).

3. acceleration

   Acceleration is the rate at which an object changes its velocity. It is a vector quantity, which means it has both direction and magnitude, and can be increased or decreased speed or a change in direction. It is typically measured in meters per second squared (m/s²).

1. Acceleration

   In physics, acceleration is the rate at which the velocity of a body changes with time. In general, velocity and acceleration are vector quantities, with magnitude and direction, though in many cases only magnitude is considered. As described by Newton's Second Law, acceleration is accompanied by a force; the force, as a vector, is the product of the mass of the object being accelerated and the acceleration. The SI unit of acceleration is the meter per second squared. For example, an object such as a car that starts from standstill, then travels in a straight line at increasing speed, is accelerating in the direction of travel. If the car changes direction at constant speedometer reading, there is strictly speaking an acceleration although it is often not so described; passengers in the car will experience a force pushing them back into their seats in linear acceleration, and a sideways force on changing direction. If the speed of the car decreases, it is usual and meaningful to speak of deceleration; mathematically it is acceleration in the opposite direction to that of motion.

1. Acceleration

   An increase in the rate of speed.

The Standard Electrical DictionaryRate this definition:0.0 / 0 votes

1. Acceleration

   The rate of change of velocity. If of increase of velocity it is positive; if of decrease, it is negative. It can only be brought about by the exercise of force and is used as the measure of or as determining the unit of force. It is equal to velocity (L/T) imparted, divided by time (T); its dimensions therefore are L/(T^2). The c. g. s. unit of acceleration is one centimeter in one second. [Transcriber's note: The unit of acceleration is "centimeters per second per second."]

1. acceleration

   The increase of velocity in a moving body by the force of gravity. A planet is said to be accelerated when its actual diurnal motion exceeds its mean. In fixed stars the acceleration is the mean time by which they anticipate the sun's diurnal revolution, which is 3′ 56″ nearly.--Acceleration of the moon is the increase of her mean motion, caused by a slow change in the excentricity of the terrestrial orbit, and which has sensibly diminished the length of the moon's revolution since the time of the earliest observations.

Examples of acceleration in a Sentence

1. John Larsen:

   I would say a watered down CEPP may be worse than no CEPP, as long as the clean energy tax credit package is in at the scale and ambition people have been talking about for months, you're already going to have increased acceleration of clean energy in America.

2. Earth Fare CEO Frank Scorpiniti:

   The acceleration of the growth really comes from the access to capital we now have with our private equity partner.

3. Jennifer Bergner:

   It was an exciting time within astronomy when ‘Oumuamua was first discovered, and it just became more and more intriguing since the more we learned about it, the harder it became to explain its behavior, as an astrochemist, my own scientific interest in ‘Oumuamua developed as models started emerging to explain its acceleration, which implied pretty unusual chemical properties of the object.

4. Jeremy Lawson:

   Our index would suggest that there was stable growth, rather than the rapid acceleration suggested by the GDP figures.

5. Andrey Kuzyayev:

   We need to make up time we have lost, cycles in any economy are the norm, not deviation. There will be a slowdown but obviously there will be acceleration later.
