WebNegative acceleration. 1.Deceleration occurs when a resultant force acts on an object in the opposite direction in which it is moving. If in a chosen coordinate system, the direction of acceleration is towards negative axis then the object is said to have a negative acceleration. 2.Deceleration reduces speed, i.e. the magnitude of velocity. WebIf the velocity and acceleration have opposite signs (one positive and one negative) the object is decelerating.
