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.

Top reviews from How Things Work: An Introduction to Physics
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!
Great introduction to Physics. I use the concepts taught in this course frequently in everyday life. Professor Bloomfield explains concepts very clearly without getting overly mathematical.
