Observe that the object below moves in the positive direction with a changing velocity.An object which moves in the positive direction has a positive velocity.If the object is speeding up, then its acceleration vector is directed in the same direction as its motion (in this case, a positive acceleration). Characterized by or displaying certainty, acceptance, or affirmation: a positive answer; positive criticism. The acceleration-time graph shows a horizontal line in the positive region of the graph (meaning a positive acceleration). Acceleration has the dimensions of velocity (L/T) divided by time, i.e. Although geometric acceleration is smoother and more conducive to large-scale accelerandi than arithmetic acceleration, there is still an upward limit on the length for which it is useful, since the rate of acceleration continues to increase throughout (for positive acceleration). tive (pŏz′ĭ-tĭv) adj. Acceleration is the rate of change of velocity. Love words?

Define positive acceleration. Psychology Definition of POSITIVE ACCELERATION: a situation wherein the successive gains as an outcome of learning or practice escalate across trials. See more. If the velocity of a body goes on increasing the acceleration is positive,but if decreasing the acceleration will be negative.The negative acceleration is called retardation. The sign of the acceleration tells you whether you’re speeding up or slowing down (depending on which direction you’re traveling). The velocity-time graph shows a line with a positive (upward) slope (meaning that there is a positive acceleration); the line is located in the negative region of the graph (corresponding to a negative velocity). 2.

The act of accelerating.

More than 250,000 words that aren't in our free dictionary A single big bang and innumerable similar finite observable universes where [[alpha].sub.-max] is the preset negative acceleration limit, not necessarily equal to positive acceleration limit [a.sub.max]. definition: Positive acceleration is characterized as the increase in the velocity rate of an object. positive-negative adjective Exhibiting both positive and negative characteristics; relating to both what is positive and what is negative in a particular respect.

Having a non-zero acceleration means having any amount of acceleration whatsoever. Today the Universe keeps expanding, but since 1998 we learned that it has a positive acceleration rate.

Abbr. n. 1. a. or acceleration = change in velocity/time.=( final velocity - initial velocity)/time.

Measured or moving forward or in a direction of increase or progress: positive steps.

Although geometric acceleration is smoother and more conducive to large-scale accelerandi than arithmetic acceleration, there is still an upward limit on the length for which it is useful, since the rate of acceleration continues to increase throughout (for positive acceleration). Other forms. The SI unit of acceleration is the metre per second squared (m s −2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.

Positive acceleration definition is - headward acceleration. Negative acceleration definition is - retardation. The method (100) further comprises force fitting (118), by a processor (910), each positive acceleration time segment and an adjacent negative acceleration time segment into a model positive and negative acceleration pair curve such that a cumulative velocity value of the model positive and negative acceleration pair curves is equal to zero.

Positive acceleration is the change in velocity of an object in the positive direction, as defined for the system. n 1.
