These are amazing videos! I love hearing someone else speak on these topics. Thanks Great job !

Just wanted to say I agree with You it's beneficial to write out full equation; Lesson 30. I find this repetion very helpful learning important and difficult concepts. Tedious buy highly effective.

Mr. Spahn please come back and save the physics society

I'm doing USESO and these videos have been a lifesaver

THANKS ALOT MR.SPAHN........

Thank you so much for your videos! They are SO HELPFUL!

00:07 Overview of math topics covered in College Physics 1: Lecture 1 02:26 Understanding Exponents in Mathematics 06:59 Review of Exponents and Negative Exponents in Mathematics 09:06 Review of fractions and their mathematical operations. 13:26 Finding common denominator to simplify fractions 15:42 Solving equations by isolating variables 20:07 Solving equations involving denominators and square roots 22:20 Square both sides to eliminate square root 26:37 Expert physics problem solvers solve problems using variables first, then substitute numbers. 28:25 Solving quadratic equations using the quadratic formula Crafted by Merlin AI.

Awesome. These mathematics reviews are exactly the refresher that I needed.

Why graphs on everything and no Cartesian coordinates ? That’s essential in College Physics.

Great lectures! There is a remark in minute 23:43 should be (30m)^2

20:36 stopped

Thank you sir for your clear and helpful instruction that I have benefited me tremendously. Btw, could you please upload the videos of those missing lectures? I have been searching all over youtube just in vain. 😭😭😭😭

"HOA, we are not talking about housing things." :) funny

I love your lectures, but I was wondering where are lectures 14-16 from College Physics II.

I am hoping to use this playlist as an Earth Science course for my homeschooled 9th grader. Does he need a certain level of math understanding to be able to understand the Earth Science material?

I belive in young earth

man.. thank you so so much. God bless you.

is this playlist algebra based physics or calculus?

Nice Lecture from Germany

Mew mew needs to remember this as I struggle in physics class.

Ty sir 🫠

I'm enjoying your Physics Lessons, but having reviewed both Physics 1 and 2 I don't see anything including friction; which is very important. Having subscribed to your videos can You recommend one of your videos or other videos?

thank you! keep up the videos

Thanks!

Thank you so much, Sir Alexander. You really helped me a lot today, and I learned a great deal.

I heard the causes of earthquakes are electromagnetism and the ionosphere.

What it says "a rope" not two ropes?????

im crying so hard rn

This American feels very strongly the United States needs to switch to the Metric system! English system of measurement grossly outdated and innefficient.

Thanks soooo much sir for the lecture

...1m + ym...

Is there a mistake or am I missing something?....coz it is stated that the 'bed' is 1m above the ground, but that's just part of the length of the'opposite'...there is also the height of the side barrier, where the hypotenuse incline rests. So, the length of the 'opposite', should be 1m(ground to bed), and ym from bed to top of barrier...

Awesome videos. Expert teaching. Just the pace of explanation required for beginners. Tqvm, master. God bless.

Your math for a teaspoon of neutron star material compared to cars on earth is wrong. 10,000,000 tons 1 car weighs 2 tons. 2500 cars weigh 5000 tons, not 10,000,000 tons. It would take 5,000,000 two ton cars to equal 10,000,000 tons, or 1 teaspoon of a neutron star's material. I'm enjoying the lecture though. I'll definitely watch all of these! I'm currently studying an online astronomy course (mostly ready) and decided to find some lectures just to change it up. I look forward to listening/watching all of them! Thank you for posting these on KZbin!

Really good job explaining. Thank you.

Hi. Your discussion is clear and informative. May I ask if you can share your slide presentation and reference book for this lecture? I am glad to adopt and use it in my undergraduate class in astronomy. Thank you.

The negative exponent rule can be thought of as 5he subtraction rule, Its x^0/x^m which becomes x^(0-m) or x^-m. x^0/x^m also = 1/x^m

Time still goes only forward 26/7/2024 😅

Do you have any lectures continuing into electromagnetic waves?

What about waves

any person tell me the earth is round the sun or sun is around the earth

Is electric potential energy also a scalar like electric potential?

thank you sir, for your lecture, it really helps a lot. i am really really really Greatfull to you!

Hello sir! I just wanted to let you know that these videos are a great help, studying for exams rn and I felt so lost bc I couldn't afford tutors or review centers... I really appreciate this playlist, it helps sm 🙏. God bless you

Thank you!

For question 3, how do the spheres remain charged despite the rod being removed?

I should of been following these lectures when i was 19. lol

This is very informative!

Science has always been an interest of mine, i tried Biology course in college which didn't work out. but now i'm totally interested in Astronomy and will be using these lectures to prepare for college. :) Thank you!
