WEEK 2
Skating
Professor Bloomfield examines the principle of inertia through skate boarding. Objects at rest tend to remain at rest while objects in motion, tend to remain in motion. Why does a stationary skater remain stationary? Why does a moving skater tend to continue moving? How can we describe the fluid, effortless motion of a coasting skater? How does a skater start, stop, or turn? Why does a skater need ice or wheels in order to skate? Physics concepts covered include Newton's first and second laws and 5 physical quantities: position, velocity, acceleration, force, and mass.

Ratings and Reviews
like this course!
A very clear, and well thought out course. I am brand new to physics and this was a fantastic way to get started. It walked me through information carefully, and I never felt lost or confused at any time. The questions and quizzes were well timed and relevant to the content, and really helped solidify information.
The only negative I can mention are some small issues with production, particularly with sound editing, but considering this was a volunteer operation and not part of a full time job I think it is perfectly forgivable.
The teacher clearly knows his stuff and is a really fun instructor, I thoroughly enjoyed this course and hope to see more of his work in the future!
Great course!
