A rhythm that emphasizes the off or irregular beats is known as syncopation.
The kind of rhythm Syncopation consists of a disturbance or interruption of the regular flow of rhythm, a placement of rhythmic stresses or accents where they wouldn't normally occur. Syncopation entails different unexpected rhythms, making part or all of a tune or piece of music off-beat.
The speed and accleration of a car travelling in reverse and in the normal direction is the same. Therefore the measurement of its speed is still done using the metric system or via miles per hour (mph).
