Wiktionary

  1. acceleration(Noun)

    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. acceleration(Noun)

    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. acceleration(Noun)

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

  4. Origin: * First attested in 1531.

Webster Dictionary

Freebase

  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.

U.S. National Library of Medicine

  1. Acceleration

    An increase in the rate of speed.

The Standard Electrical Dictionary

  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."]

  4. Klevis Ylli:

    For the indoor navigation system, there are sensors [accelerometers] within the shoe that determine how fast you're moving, acceleration and the angles that your foot has traveled. And from this data, the system can calculate the path that you have walked.

  5. Damian Real:

    Basically what it does is that it has a central part, LED lights which are lit all the time. When the cyclist moves to the left it activates the indicator on the left side. When the right arm is moved it activates the indicator on the right side. This system has two forms, one which is prevention and to illuminate and the other is an alert system. This system connects to mobile phone sensors so that when there is a change in acceleration it sends those registered details that there is a change in acceleration and probably an accident and a location where the cyclist can be found. So it has two things, firstly prevention and the other is an alert system in case of an accident.
