Physics courses and the path from Grade 10 to Grade 12

Compare Ontario SNC2D, SPH3U, and SPH4U physics pathways, their key topics, and free reviewed lessons. Find motion, forces, energy, waves, and fields.

Which course should you open?

SNC2D · Grade 10 Science

Build scientific investigation skills and introductory physical-science concepts before choosing senior physics.

Open SNC2D
SPH3U · Grade 11 Physics

Study motion, forces, energy, waves, sound, electricity, and magnetism.

Open SPH3U
SPH4U · Grade 12 Physics

Extend mechanics into momentum, fields, wave optics, and modern physics.

Open SPH4U

برای انتخاب درس مناسب، کد برنامهٔ درسی مدرسه را بررسی کنید: علوم پایه دهم SNC2D، فیزیک پایه یازدهم SPH3U و فیزیک پایه دوازدهم SPH4U یکسان نیستند.

One graph, three different quantities

When reading motion graphs, check the axes before using a formula. The slope of a position–time graph gives velocity; the slope of a velocity–time graph gives acceleration; and the signed area between a velocity–time graph and the time axis gives displacement. For instance, a constant velocity of 3 m/s for 4 s gives a displacement of 12 m. The units help distinguish slope from area.

در نمودار مکان–زمان، شیب سرعت را نشان می‌دهد؛ در نمودار سرعت–زمان، شیب شتاب و مساحت علامت‌دار زیر نمودار جابه‌جایی را نشان می‌دهد. همیشه محور و یکا را بررسی کنید.

How the topics connect

Begin by describing motion with vectors and graphs. Then draw a free-body diagram and connect net force to acceleration. Use work and energy when forces act through a displacement, and conservation of momentum when interactions happen over a short time. Later courses add fields, wave optics, and modern-physics models. A named topic on a course map has a written lesson only when it is marked published.

مسیر یادگیری از توصیف حرکت با بردار و نمودار آغاز می‌شود، سپس نیرو و شتاب، کار و انرژی و در درس‌های بعدی میدان‌ها و نور بررسی می‌شوند. تنها درس‌هایی که «منتشرشده» هستند متن آموزشی کامل دارند.
