Define the branches of classic physics
(mechanics, thermodynamics, electricity, magnetism, optics and acustics).
Mechanics: Studies the movement of bodies, divided between kinematics and dynamics.
Thermodynamics: Responsible for studying the phenomena related to heat.
Electricity: Branch of electromagnetism, which deals with magnets and magnetic fields caused by moving electric charges.
Optics: Responsible for analyzing all re4lated to light and colors.
Acustics: Studies and is related to sound, its origin and its propagation.
