Pendulum problem using conservation of energy

As a pendulum swings back and forth, how high does it go and what is it's maximum speed?

Thank you very much for the detailed and easily understandable explanation. I am taking an online Mechanics course and I realized its quite difficult to learn Physics through only a textbook or online articles. This definitely saved me a lot of time and frustration.

Matt! Thank you so much! My name is Matt too, however, I am stupid:( . Have a great day!

Your presentation is unique! Brilliant explanation!

[jvillalobos]

amazing!!!! it couldn't be explained simpler than this!

[tony-iqhl]

Explained clearly, helped me a lot for my assignment. Thanks!

It is important to know that the calculations are made at the bottom h=0 so v is the velocity of the mass along the bottom point when it is launched at rest from an angle \theta. This is not the formula for the velocity or kinetic energy at any point of the trajectory of the pendilum. Great video openened my eyes!

I’m mesmerised by how well he can write backwards

[ptyptypty]

and so it another clear, concise video.. THANK YOU...

holy physic emperor, thanks for your great work

[innovationsforall]

Fantastic explanation! Thanks for sharing!

Good video. If you could include energy bar chart, this will be good.

this is a great explanation, thank you

Hi sir great video. I just have one question when Rearranging h=L-cos theta why does it become L(1-costheta. Where does the 1- come from?

Did he stop posting vids? He was posting a lot a few months ago, and suddenly stopped.

[noahjmeyer]

this is awesome, thank you! also, did you have to write everything backwards?
