Grade 11 Physics · SPH3U
How the course connects
Five worlds, one question each, in the order the ideas need. Each world grows out of the one before it; the line between them says how.
The five worlds, in order
You can now describe how velocity changes. Next: what makes it change.
Forces
Why does motion change?
3 topics
You can predict how a force changes motion. Next: what the force hands over while it does.
Energy
Where does the ability to make change go?
5 topics
Energy moves from store to store. Next: how it moves through a medium without the medium going anywhere.
Waves & Sound
How can a pattern carry energy and information?
3 topics
A wave carries energy without carrying the medium. Next: charge carries it round a loop, and the loop always balances.
Electricity & Magnetism
How do charges, fields and changing fields make circuits and machines work?
4 topics
Ideas that keep coming back
Each one is taught once, on a card, and then used again in later worlds. Reopen any of them.

Every experience, as a sky
Five constellations, one per world — and each dotted line is the SUGGESTED ORDER: follow the numbered lesson stars to learn, in sequence. Finish a lesson and its star ignites. Squares are labs, rings are games: pure play, always open.
