Abstract

The activities of the track and the field are important events in the field of sport because of these
events of personal and international benefits and fun for spectators as well as recreation and fitness,
and throwing events part of the track and field events where the achievement depends on the
distance cut by the equipment, and because the tool is thrown is subject to the laws of projectiles In
terms of the existence of important conditions, which consists of three factors (speed, height, and
angle of release), and these three factors are found in the Basic Law of the projectiles.
The knowledge of the relationship between changing the values of the three factors and
achievement is important for the purposes of movement analysis, training and learning. Speed is the


main factor in this law in addition to both the angle and height of release, that the provision of speed
of launch requires the exercise according to the training modules for development, and the height of
the release depends on the length of the thrower and the possibility of extending the arm within the
appropriate anatomical range and according to the sequence of parts performance.
The large difference in the speed of the release of the tool or the height may cause some
problems in the law and thus do not match the real achievement with the distance resulting from the
law. The aim of this research is to analyze the basic law of the Projectiles when different levels of
release and landing and the statement of the best law and then compare the achievement achieved
and distances from the basic law and some other laws and find the appropriate angles.
The researcher concluded that the current laws do not respond to the real achievement in most
cases, and that the angle that some laws deal with does not give justification for adoption, and can
modify some laws, and the angle 33 degrees can be the best angle of the three events
