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.

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.
由 AA 提供Sep 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.
由 KC 提供Jun 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.
由 VL 提供Sep 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.
由 JR 提供Apr 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.
由 MM 提供Feb 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.
由 HH 提供Jan 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.
由 J 提供Apr 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.
由 DC 提供Feb 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! :)
由 SK 提供Nov 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.
由 AD 提供Oct 18, 2017
For people starting out in physics who want to learn the physic concepts, jump right in! This course will help you get ready for a math intensive physics course after this.
由 ME 提供Jul 10, 2017
Excellent course, enjoyed the professor's lecture style. Also,learned and understand far more about the physics of how things worked then I did before taking this course!
由 BD 提供Nov 21, 2019
Unfortunately I wasn't able to afford the certificate. But the lectures were very helpful and fun! I learned a bunch! I also had your book, which was amazing!\n\nThanks!
由 ZA 提供Oct 28, 2015
I just love this course.... It's helped me a great deal in getting a grip on the subject. I greatly appreciate all the effort Prof Bloomfield put in to make these :)
由 DB 提供Jan 6, 2017
Too good....actually I am 14 and I have a great interest in Physics...I really fell in love with this course...The explanation, experiments are really appreciable..
由 ES 提供Dec 5, 2018
This was an excellent course with thorough material and an excellent evergreen physics professor who made the learning so much more fun. Highly recommend it
