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
I find this course simple to follow and well taught by the professor because it associates daily objects and incorporates such complexity in the simplest format so I can follow.
Awesome course, very intuitive and practical lessons from professor Lou made me understand the concepts really good
Love the course. Energetic and brilliant instructor! Easy to understand, even for me, someone who learned Eng as the third language, someone who currently has a 15mo, and someone who had never paid attention in Physics classes growing up. (Hmm, musician, just typical!) I, however, do have two suggestions, if I may:
I would suggest to unlock the quiz. I know that it's a paid content. But, isn't Coursera a place that encourages learning instead of learning for a certificate? Those who want the certificate could pay for it after they are done with the class.
Forgive me if someone else has already mentioned this: In the early class, there was a video showing Lou running up stairs and stops. I think it would be fair, if we also considered the very beginning moment(still) to start running. (I think the options started from "already" moving instead of from no movement to movement)
I certainly hope to take more classes by Louis from now on. (Yes, feel free to quote me in the petition!)
