Where can I take a general physics course 101 at online?

Click For Summary

Discussion Overview

The discussion centers on finding suitable online general physics courses, particularly those that start with algebra. Participants explore various course options and express differing opinions on the necessity of calculus for understanding physics concepts.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • Some participants suggest Khan Academy as a potential resource for physics courses, though they have not explored it in depth.
  • One participant shares their experience that studying Freshman Physics in an algebra-only context was challenging and recommends completing Calculus I and II first to ease the learning process.
  • MIT OpenCourseWare is mentioned as a resource, particularly for those who have knowledge of calculus.
  • Another participant notes the lack of algebra-based physics courses online but points to OpenStax for high school physics texts that use algebra.
  • Saylor Academy is highlighted as offering PHYS 101 and PHYS 102, which are calculus-based but may be manageable without calculus for mechanics.
  • There is a debate regarding the necessity of calculus for understanding mechanics, with some expressing skepticism about managing without it.
  • Historical context is introduced regarding the development of calculus by Newton and its relation to physics, with references to the history of electronics and electromagnetism.
  • One participant expresses confusion over terminology used in the discussion, specifically regarding the term "electronics" versus "electromagnetism."
  • The original poster expresses a preference for learning calculus before tackling physics, citing concerns about the quality of algebra-based courses.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether calculus is necessary for understanding mechanics, with multiple competing views presented. The discussion remains unresolved regarding the best approach to learning physics online.

Contextual Notes

Some participants express uncertainty about the effectiveness of algebra-based courses and the prerequisites needed for a solid understanding of physics concepts. There are also unresolved discussions about the historical context of calculus and its application in physics.

Summary:: Where can I take a general physics course 101 at online?

Looking for a general physics course that starts with algebra that I can do online.
 
Physics news on Phys.org
I think Khan Academy is good. Although I haven't looked at their physics courses in depth.
 
I first studied Freshman Physics in an algebra only setting, and frankly, it was unnecessarily hard. I would suggest that you first get Calc I and Calc II behind you; then Freshman Physics will be much easier and make a lot more sense.

I do not know of any algebra-based physics courses online. I believe OpenStax has high school physics texts with only algebra.

I think you would be better served by learning algebra and trigonometry and then learning calculus. There's actually a number of good online lectures for beginning physics.

Single and Multivariable Calculus.

https://ocw.mit.edu/courses/mathematics/18-02sc-multivariable-calculus-fall-2010/

Linear Algebra.

Differential Equations.

For physics,

Classical Mechanics.

Mechanics and Thermodynamics.

Electricity and Magnetism.
https://ocw.aprende.org/courses/physics/8-02-electricity-and-magnetism-spring-2002/

The next two are from Fundamentals of Physics by Ramamurti Shankar at Yale,

Mechanics, Waves, Relativity, and Thermodynamics.


E&M, Optics, and Quantum Mechanics.


Lots of good stuff.

I think that is doubtful. Newton did not invent calculus in order to do electronics.

Electronics? I suppose it is mechanics. A quick Google gave me the following.
Electronics' actual history began with the invention of vacuum diode by J.A. Fleming, in 1897

Really??

Newton came to calculus as part of his investigations in physics and geometry. He viewed calculus as the scientific description of the generation of motion and magnitudes. In comparison, Leibniz focused on the tangent problem and came to believe that calculus was a metaphysical explanation of change.
Wikipedia result on history of calculus. Correct me if I am wrong. Benjamin Franklin discovered charge in 1740's and the study of electronics was began in 1897 by the invention of Vaccum diode by J.A. Flemming.

PHYS 101 is Intro to Mechanics and PHYS 102 is Intro to E&M. I believe what Dr. D is saying is that it is doubtful that you can manage mechanics without calculus since Newton initially came up with calculus to deal with mechanics, not E&M.

Mr. Husky: Note the essential "not" in Dr. D's response.

Sorry for my English. Yeah I understood what Dr. D was saying. I am quite confused when he/she said "electronics". It should be electromagnetism. Though this is not a discussion at all. Just I am trying to learn some history.

OP: I'm in the camp that would advise you to learn calculus first. Too much vague, hokey hand-waving in algebra-based courses (along with frequent, annoying instances of "Here is the formula for ... You will just need to accept it blindly for now, because you will need to learn calculus first to derive it.").
