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.

A brilliant teacher makes a course easy, makes you wish learning his lessons without too much effort from your side, this being the case here, I really enjoy this course and I find it useful.
C 제공Oct 27, 2018
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!
WY 제공Jun 21, 2017
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.
AA 제공Sep 11, 2017
The course was utilized as a template for teaching physics in an after school program. I enjoyed taking the class and obtained some creative ideas for teaching basic physics principles.
KC 제공Jun 18, 2017
I am a homeschool mom to an 11 yr old boy. He took this course and really enjoyed it. The demonstrations of physics at work made the information very intersting and accessible to him.
VL 제공Sep 22, 2016
this course brings to me a explanatory answers to the ordinary physical works surrounding us, i can say that is a fundamental stuff for beginner who love physics. It's naturally good.
JR 제공Apr 18, 2016
I love the course. Professor Bloomberg makes me love this class. I am glad to take the class with him since I need to learn physics to learn astronomy. Thank you professor Bloomberg.
MM 제공Feb 16, 2020
Very good course for introducing the basics of main physics' aspects in your real life, however, as well very entertaining. Hope to be able to participate in the next session soon.
HH 제공Jan 22, 2018
This course really helped strengthen my physics concepts and really helps you understand physics. This course is for people that need to understand the basics concepts of physics.
DC 제공Feb 26, 2019
I'm a secondary school teacher of physics, and I've got and collected a lot of new ideas of approaching things. I will use them in my teaching practice.\n\nThanks, professor! :)
J 제공Apr 8, 2018
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.
SK 제공Nov 9, 2016
One of THE best courses I have done so far online. Wish the good Prof would offer other courses in Physics. He has a nice and simple way of putting across the scientific stuff.
