Learn Physics College Text Book
Physics, then, means studying nature at its most base level - matter, behavior and motion, energy types, time and space, and their actions and interactions. It has gone from an inextricable link with chemistry and biology, and even natural philosophy prior to the Enlightenment to becoming a major force in its own right in the scientific age.
Physics can also be described as the science dealing with physical quantities. In this regard, physics is widely considered to be the most fundamental (and important) of all the natural sciences. After all, physics pertains to the quantification of almost all matter that exists in this world. It is any aspect of nature that can be expressed, measured or calculated in specific terms. An appreciation of the world we live in and all its elements that can be observed by the five physical senses could be considered as physics in its most general sense.
