Physics represents one of the most interesting scientific disciplines that are explored not only by the engineers or those that design civil objects and offer certain services. If you are stuck with equations or have specific questions, you should start by browsing through the advanced physics answer. You can approach the posts as the Physics equation solver to receive free help as you can compare what you already have with the posts that are related to your subject or objectives. There are also atomic physics questions that have been resolved where the knowledge of Physics comes first.
