Introductory Physics.
Physics is one of the broad categories of science. The other significant specializations include biology and chemistry. These three studies help us in understanding and exploring everything found in the universe. This subject deals with the composition of matter and energy. It deals with physical and natural occurrences such as the formation of a rainbow, the cause of the sun rising and setting, the reason behind fall of things from upwards to downwards, compositions of shadows and eclipses among other phenomena.
Divisions of Physics.
Physics as a branch can be divided into other smaller chapters as will be discussed below:
Atomic physics – it deals with the study of atoms, electrons and the nucleus. It deals with how particles are arranged and the processes that come as a result of these arrangements.
Thermodynamics Physics – it deals with heat and temperature in relation to energy and composition of matter.
Waves – deals with change that is brought about by the application of a force on a stable element. Examples of waves include mechanical and electromagnetic waves.
Mechanics – this deals with motions resulting from application of a force. These movements can either be linear, circular or oscillatory.
Magnetism and Electricity – this branch deals with the relationship between electric and magnetic fields.
Geometrical Optics – this branch deals with light in different media
