The 'sprocket' is the projection or tooth on the wheel. A 'cog' is a wheel with a series of projections, or sprockets. BUT a 'cog' can also refer to the individual projections on the wheel, and, and a 'sprocket wheel' can refer to a wheel with teeth. So effectively, they are interchangeable.

A sprocket is a sprocket. That's a round thing with teeth around it to engage a chain. It does not even have to have anything to do with bicycles. In bicycle parlance, the "sprocket" on the front is called a chainwheel. Some people call the one(s) on the back a cog or cogs, but in my mind a cog is acually a tooth on a sprocket (or gear). Maybe calling a sprocket a cog is typically North American. Anyone from Over 'Ome have any input on that? It's been over 50 years since I left.
