Course Description:
PHY 104 Premedical Physics (3 C.H: 3 lectures)
This premedical general course of
physics introduces the students to mechanical aspects of physics such as force,
gravitation, Density, Newton’s first and third laws, equilibrium, Newton’s
second law, Friction, torque,
static equilibrium, center of gravity, Levers and muscles. Elasticity including
Stress, Strain and Young’s Modulus are also presented. The
students will understand the temperature
scales, molecular masses, pressure, and the principle of ideal gas law. Human metabolisms,
Radiation, Temperature regulation in warm – blooded animals are other phrases
need for the premedical student. Fluid mechanics including Archimedes’
Principle, Continuity Equation, Streamline Flow, and Bernoulli’s Equation will
be presented. The role of gravity in the circulation, Blood pressure using the
sphygmomanometer will be given. Viscosity, Flow in the circulatory systems and Centrifugation
are applications on fluids. The structure of nerve cells, the resistance and the
capacitance of an axon, electroencephalography and electrocardiograph are given
as applications. Sound waves including the nature and speed of sound, sound
detectors, auditory response, and ultrasound are presented. Light including the
index of reflection, reflection and refraction, total internal reflection
principles will be given. Concentration on the X-Ray diffraction and the
structure of biological molecules are
given as applications. In geometric optics; Mirrors, lenses, and the power of
the lenses will be given. The aberrations, human eye, tomography, imaging a
slice, optical defects of the eye will be given as applications. The students
will be faced to some applications in radioactivity, half-life, dating in
archaeology and geology, radioactive decays as part of their knowledge in
physical phenomena. Ionizing radiation will also be explained including the
interaction radiation with matter, radiation units, harmful of radiation,
chronic radiation exposure and radiation in medicine.
