Contributions: 

He proposed an explanation of the acceleration of falling bodies by the accumulation of successive increments of power with successive increments of velocity.

Abu’l-Barakat also developed Philoponus’ theory of impetus, stating that the mover imparts a violent inclination (mayl qasri) on the moved and that this diminishes as the moving object distances itself from the mover.

Al-Baghdadi also suggested that motion is relative.

He redefined the concept of time as “the measure of being”, thus distinguishing between space and time, and reclassifying time as a metaphysical concept rather than a physical one.

Al-Baghdadi’s most significant departure in psychology concerns human self-awareness.
