*It can be positive (speeding up) or negative (slowing down), also called deceleration.
*[[Measure]]d [[Metres per Second per Second|metres per [[secondsquared]] squared (m/s²).
*[[Acceleration]] be caused by changes in [[speed]] or direction.
*[[Newton]]'s Second Law states that [[acceleration]] is produced when a force acts on a [[mass]] (F = ma).
*[[Acceleration]] can be uniform or non-uniform.
*The direction of the [[acceleration]] vector determines the direction of the change in velocity.
*[[Centripetal Acceleration|Centripetal acceleration]] occurs when an [[object]] moves in a circular path and is directed towards the center centre of the circle.*[[Gravitational Acceleration|Gravitational acceleration]] near the [[Earth]]’s surface is approximately 9.8 m/s².
