Frictional Forces: Static and Kinetic

Newton's first law tells us that an object in motion will remain in motion, but we don't really see that on earth, do we? If you throw a ball, or push a hockey puck, these things do eventually stop. Why? To answer this we must learn about static and kinetic friction!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

this guy carried me through sophomore year chemistry and now he's carrying me through junior year physics

I did a short experiment. I watched this video 2 times: yesterday night and tonight.

Yesterday, I understood everything he said but couldn't get anything inside my head. So I used the whole day today to read the book and solved many maths related to frictions.
Tonight as I watched this video again I was able to understand everything loud and clear😁. Thanks professor Dave

This is like a crash course but nothing about it is too clumped. Perfect, straight-to-the-point, and easy. Will subscribe and listen to you religiously throughout my physics course. Thank you.

Professor Dave, your videos got me through physics 1 and 2 in my post-bacc, and as I'm studying for the MCAT I found myself needing additional explanation. The jingle came to my mind and I knew exactly where to go. So thankful for you and your videos!

Is it sad or impressive Dave can teach in 5 minutes what my professor can’t in 3 3 hour class periods?

[andresjr.baybay]

thanks a lot bro. this new subscriber is from the Philippines, the way you deliver the topic is so smooth, wonderful and easy to understand. thanks a lot. static & kinetic friction topic. great!

Unfortunately, my prof doesn't teach anything... so I am very thankful for your videos with visual aids! I hope you keep making more!!! Yours are by far the best on youtube! :)

[lianethlozano]

Your videos are so helpful, thank you so much!

[stovegamesgames]

I swear without this video I would be super lost in my physics class

Thanks, dave. At this current time, i have a hard time learning about frictional force in orthodontic. And ur explanation makes me a little bit confidence. I understand the first 5:30 minutes, the rest remains a question for me. Thx

[newtube]

Lots of new ideas thank you . It's relevant in my study

We could see how much effort you put into creating a video.
Super.👍
We A4Q team with your growth.
Full support 💪

This Guy explained these concepts in just 8 minutes which I am Trying to understand from 2 weeks

[AqibAli-hdxp]

thank you dave my physics teacher didn't explain in this way as you explained . thank you very much

[elfigahleitner]

thank you so much for sharing your knowledge with the world :D! now it all makes sense :)!!

[IgnitedIce]

Thank you so much, I was stuck on a question and this video helped me a lot!

[SifulIslam-jooe]

This is my first video of yours and I subscribed as soon as I saw it at a glance 😊

[pubuduweerakoon]

Concepts are simply built...Thanks Sir..

[henrylopez]

thank you man, i am teaching my nephew vectors and this video helps a lot to illustrate parts of the whole idea. thank you.

[humaidalsuwaidi]

Thank you, You’ve helped me understand the difference between the frictions.
