Acceleration

• The rate at which the velocity of an object is changing.
• is the rate of change in velocity with respect to time. Acceleration is also a vector.
• Change in velocity of a moving body or the rate of such change, positive or negative in relation to a known position of reference.
• Science: in general, any increase in the speed or rate at which some process occur; in technical use acceleration and speed are not synonymous.
• Change in velocity over time. Used in incremental animation.
• The changing of the speed and/or direction of an object.
• The change in the velocity of a body or particle with respect to time. The parameter that an accelerometer measures (dv/dt). Units expressed in "g".
• an increase in rate of change; "modern science caused an acceleration of cultural change"
• the act of accelerating; increasing the speed
• (physics) a rate of increase of velocity
