So id like to do physics without changing my major (or would it make a difference?) what is the basic starter class/course for anyone intrested (in a college setting) in said science?
You can try out the physics courses from the khan academy. Those can be accessed from the youtube. Alternatively they also have the official website out which you can check out.
The basic starter course for Physics in a college setting is usually an introductory course such as Physics I or General Physics. These courses typically cover introductory topics such as kinematics, dynamics, energy, momentum, and electricity and magnetism. Some universities may also offer a more specialized course such as Mechanics or Waves and Oscillations.
The way in which people interested in physics use it may vary. However, one starter course that can be of assistance to those interested in the subject is the tutorial series "How to Do Physics" by the magazine Mid-America University Press. This series provides a guide to starting with the basics of physics, with the first book being Introduction to Physics, second being called "The Science of Time," and the final book being "The Science of Gravitation."
