A block of mass 1.3 kg is attached to a spring whose force constant,
Videos like The equation of a wave are unnecessary to watch if you're comfortable with trigonometry.
Today and yesterday I worked on the start of oscillations and waves. A lot of it is trigonometry, which I am very comfortable with, so it's just a bit of review. It's nice to see it used in the real world though. I feel that it would have been nice to have a better understanding of calculus before taking physics too. I might try to complete the khan differential and integral calculus courses before continuing on with more advanced physics after this physics course.
Today I learned about sound wavelengths, periods and the speed of sound. There are 4 video's at the beginning of this section that kind of introduce sound. I think it would be good to do some practice about sound properties after watching the 4th video which I'm doing next time.
A cool resource for more on sound as a mechanical wave http://www.physicsclassroom.com/class/sound/Lesson-1/Sound-is-a-Mechanical-Wave
I completed the 4 sound videos, this resource is great for more information and practice questions: http://www.physicsclassroom.com/class/sound/Lesson-2/The-Speed-of-Sound
today I learned more about the speed of sound and did some practice questions about that. I also larned about decibels and mach
