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.

Best online physics intro course I've taken - explains physics through first principles and does not require math
Professor Bloomfield is a great teacher and his lessons are so fun and explained in short and succinct manner.
Professor Bloomfield was great, this is a perfect class for reviewing concepts or for someone like myself as an introduction to physics I missed in high school and junior college. I really needed the course to improve my physics terminology more than conceptual understanding, though I am certain I improved both. Thank you Professor Bloomfield!
The course was simple and easy to follow! I enjoyed Professor Bloomfield's teaching very much! I definitely would recommend it for anyone who is curious about the basic principles of science!
