Good to see you up here Will_Iam!
If you need a little help with the terminology then you may wish to proceed in the following order:
When you get into the watch course click on the “Why Watches Work” link.
After going through that move on to “Escapement Action”. This one may take a little while to get through but it’s worth the effort to get a good understanding of what’s covered.
Then go to “Safety Action”
…and finally “Motion Works”.
If you go to the videos after all of this you should have a pretty good understanding of what’s being covered. By going back and forth between the videos and the text things will begin to sink in…takes a little while but you’ll get there. If you need any help at all just let me know here on the forum and I’ll do my best to help out.
