Question: What does the subject Physics study?

The philosophy of thermal and statistical physics is that part of the philosophy of physics whose subject matter is classical thermodynamics, statistical mechanics, and related theories.
Its central questions include: What is entropy, and what does the second law of thermodynamics say about it?
Does either thermodynamics or statistical mechanics contain an element of time-irreversibility?
If so, what does statistical mechanics tell us about the arrow of time? 
Thermal physics is the combined study of thermodynamics, statistical mechanics, and kinetic theory.
This umbrella-subject is typically designed for physics students and functions to provide a general introduction to each of three core heat-related subjects.
Other authors, however, define thermal physics loosely as a summation of only thermodynamics and statistical mechanics. 
The subject of counterfactual definiteness receives attention in the study of quantum mechanics because it is argued that, when challenged by the findings of quantum mechanics, classical physics must give up its claim to one of three assumptions: locality (no "spooky action at a distance"), counterfactual definiteness, and no conspiracy.
If physics gives up the claim to locality, it brings into question our ordinary ideas about causality and suggests that events may transpire at faster-than-light speeds.
If physics gives up the "no conspiracy" condition, it becomes possible for "nature to force experimenters to measure what she wants, and when she wants, hiding whatever she does not like physicists to see.
"If physics rejects the possibility that, in all cases, there can be "counterfactual definiteness," then it rejects some features that humans are very much accustomed to regarding as enduring features of the universe.
"The elements of reality the EPR paper is talking about are nothing but what the property interpretation calls properties existing independently of the measurements.
In each run of the experiment, there exist some elements of reality, the system has particular properties < #ai > which unambiguously determine the measurement outcome i >, given that the corresponding measurement a is performed."
If physics gives up locality, that amounts to admitting the possibility of sudden "magical" intervention in human affairs from unknown and possibly unknowable sources of action.
Something else, something that may be called "counterfactuality," permits inferring effects that have immediate and observable consequences in the macro world even though there is no empirical knowledge of them.
One such example is the Elitzur-Vaidman bomb tester.
These phenomena are not directly germane to the subject under consideration here. 
Eureka!
is a series of humorous animated shorts that illustrate concepts in physics.
Each program takes a simple and direct approach to the subject matter; while the basic concepts are explained in a voice-over, cartoon characters and a variety of animated objects demonstrate the principles on the screen.
Constant review and reinforcement make the message clear; as a result, the study of physics becomes easy and accessible - even to viewers without a solid background in the subject.
Basic formulae and concepts are introduced with a recap of what was learnt in the previous episode to build knowledge on a topic and create connections.  
The SAT Subject Test in Physics, Physics SAT II, or simply the Physics SAT, is a one-hour multiple choice test on physics administered by The College Board in the United States.
A high school student generally chooses to take the test to fulfill college entrance requirements for the schools at which the student is planning to apply.
Until 1994, the SAT Subject Tests were known as Achievement Tests; until January 2005, they were known as SAT IIs; they are still well known by this name.
The material tested on the Physics SAT is supposed to be equivalent to that taught in a junior- or senior-level high school physics class.
It requires critical thinking and test-taking strategies, at which high school freshmen or sophomores may be inexperienced.
The Physics SAT tests more than what normal state requirements are; therefore, many students prepare for the Physics SAT using a preparatory book or by taking an AP course in Physics.
