I’m not even taking this class but I just watch these videos to support this great man

[MoosiesMusings]

I really hope you continue this series! Impulse and momentum would be great, I have a really bad dynamics professor and this whole COVID 19 stuff has made him even more useless. Your videos are a lifesaver and you've helped me so much with assignments and understanding! Thanks so much for all that you do, sending good vibes your way man

[CavernCityRenFest]

I got my bachelors in industrial engineering from Texas Tech but sadly could never get a class with Dr. Hanson. Everyone loves him!

[dudeisawesome]

thank goodness Dr. Hanson!!!! You uploaded this on perfect time, getting close to midterm for my dynamics class

[troyhanes]

Perfect timing Dr. the exam is in 3 days. I’ve watched your videos since your static’s series and it is always extremely helpful

[Kirstyish]

WOOHOO! Just in time for our exam in Dynamics in 2 days. Thank you sir!

[chasetherightenergy]

My whole country's in lockdown right now so these videos are really helpful. Thanks!

DR. Jeff Hanson, thank you for a classic selection and analysis of another solid example of Work and Energy in old fashion Dynamics. I really like these problems in Engineering Physics One and Dynamics.

Hey doctor Hanson the .5 should be squared right? Then the -90J for the Uspring makes sense. Also thank you so much for this video and all your videos for that matter, you are amazing and I tell people about you all the tine as you are the professor I dream about having for this class!

[abdirizak]

I have come this far in my Dynamics course because of you. Please keep on putting out more content.

[Dogface]

Freedom Units is a game changer. Genius

[johnpaulkiggundu]

Mr. Jeff
May God bless you abundantly for continuously helping us with all this engineering content right from thermodynamics, materials, statics and now dynamics.

[adama]

Jeff Hanson explains stuff so clearly!

[hannahgodspeed]

Please please make a lecture on Impulse and Momentum

[nicolascaleroarteaga]

I don't even need to read the book or go to class. Thanks a lot for all the videos, it's so clear and the way you share knowledge is awesome. My physics teacher was like that, I didn't know what to study on high-school last year, and this guy explained so awesome physics with the reality that make me study mechanical engineering.
❤️‍🔥

[waldemarbravo]

thanks Dr. Hanson!!! Can you do impulse and momentum

[muafenlor]

This made a lot more sense then what my professor did in class. Thank you

[paulatreides]

What about the friction force, I suppose we're assuming a frictionless plane? It would be a negative force acting against the path of the applied force, but I suppose you would need a coefficient of kinetic friction to solve and substitute into the "Fun" equation.

Plz we need more videos on thermodynamics

[mehmeterkisi]

Waiting for the rest of the series. Thank you very much!
