Information about Hibat Allah Abu'l Barakat Al Baghdaadi

Hibat Allah Abu'l-Barakat al-Baghdaadi (c. 1080-1165) was a Muslim philosopher, physicist and scientist of Jewish-Arab descent from Baghdad, Iraq. His Hebrew name was Nathanel. He wrote a critique of Aristotelian philosophy entitled al-Mu'tabar. His thought influenced another Jewish philosopher, 'Izz ad-Dawla Ibn Kammuna. It is known that Abu-l-Barakat had converted to Islam later in his life.

According to A.C. Crombie, al-Baghdaadi was a follower of Avicenna, who

proposed an explanation of the acceleration of falling bodies by the accumulation of successive increments of power with successive increments of velocity.[1]


According to Shlomo Pines, al-Baghdaadi's theory of motion was also

the oldest negation of Aristotle's fundamental dynamic law [namely, that a constant force produces a uniform motion], [and is thus an] anticipation in a vague fashion of the fundamental law of classical mechanics [namely, that a force applied continuously produces acceleration].[2]


Al-Baghdaadi's theory of motion was vaguely foreshadowing Newton's second law of motion, by distinguishing between velocity and acceleration and for showing that force is proportional to acceleration rather than velocity.

acceleration is defined as the rate of change of velocity, or, equivalently, as the second derivative of position. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in metres/second² (m·s-²).

velocity is defined as the rate of change of position. It is a vector physical quantity, both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per second (m/s). The scalar absolute value (magnitude) of velocity is speed.

In physics, force is an action or agency that causes a body of mass m to accelerate. It may be experienced as a lift, a push, or a pull. The acceleration of the body is proportional to the vector sum of all forces acting on it (known as net force or resultant force).
