Choosing the Right Physics Class: A Guide for High School Students

High school students often grapple with decisions about which classes to take, particularly when it comes to science. Choosing the right physics class can be particularly daunting, especially when deciding which one to take first. This guide aims to help you make an informed decision about your physics education.

The Importance of Appropriate Preparation

At my school, we take physics in freshman year, but having a background in basic science from middle school didn't significantly help. In middle school, we had taken pre-algebra and algebra, with most students also taking geometry. Some students had already taken geometry, providing them with a better understanding of trigonometry. The trigonometry we covered in physics was minimal, focusing mainly on using angles and the Soh-Cah-Toa method.

Required Prerequisites

When making the decision to take physics, it's important to consider your math level. If you are taking Algebra 1 or Math 1 simultaneously, you'll find physics challenging. I took physics sophomore year after completing biology and chemistry freshman year, which provided a background in some basic sciences. Physics can be tricky, and a solid understanding of biology and chemistry can be useful in problem-solving.

Mathematics Involvement

Physics is not just a math class; it requires a deeper understanding of mathematical concepts. In my experience, I took math analysis for one semester, pre-calculus for another, and still found physics to be quite tricky. The class integrates math with a variety of science concepts, which can be difficult to master. Therefore, it's crucial to have a strong math foundation.

Classical Mechanics and Beyond

Depending on your interests and future goals, you might consider starting with classical mechanics, followed by electromagnetism or nuclear physics. These subjects often have a large crossover with chemistry, making them a good choice if you are also taking or planning to take chemistry.

Ontario High School Curriculum

For students in Ontario, Canada, here is the typical curriculum for science courses in grade 12:

English (ENG4U)

Required for almost all university programs, this course emphasizes critical thinking, comprehension, and analysis of literary texts and media works.

Advanced Functions (MHF4U)

A strong math background is crucial for many university programs. This course covers functions and their applications, including algebraic, exponential, and trigonometric functions.

Calculus and Vectors (MCV4U)

Another critical math course, MCV4U prepares you for university-level calculus. It covers concepts such as derivatives, integrals, and vectors, which are essential for physics.

Physics (SPH4U)

Especially useful if you're majoring in physics, this course covers mechanics, waves, electric and magnetic fields, and nuclear physics.

Chemistry (SCH4U)

Also highly useful, this course covers the structure of matter, chemical reactions, and experiments. Some universities require at least two science courses for admission.

Biology (SBI4U)

SBI4U covers topics such as cell biology, genetics, microbiology, and evolution. It's particularly useful for students interested in biology, medicine, or related fields.

Recommendations for University-level Courses

Do not take any physics classes during your freshman year in college. Focus on getting your basics down and building a strong foundation before advancing to more complex subjects. Starting your sophomore year is a better time to take advanced physics courses.

Conclusion

Choosing the right physics class is crucial for your academic and career path. Consider your math levels, future goals, and the prerequisites required for the courses you are interested in. Remember, having a solid background in basic sciences and math can significantly enhance your understanding and success in physics.
