    I worked through this video with you this morning before my PHYS160 Final and 1 of my 4 free response questions was identical to your rotational KE example. Crushed it. You're the man!

      Glad the channel helped you - Keep on crushing!

    To clarify for those who chose to do the last problem by using the torque as opposed to net work = delta KE rotational, I believe the torque is actually 100 Nm. You still end up getting -40,000 J as your answer. Thank you, sir, as always!

    Hey when will the website be back up? I saw that it’s down right now.

      Routine maintenance being done this evening from 8pm-1am PT. My apology for the inconvenience.

    Hey are you planning to make a video about Steiner's theorem?

    For the sphere rolling down, isnt it wrong to use conservation of energy since there is friction (to make it roll and not slide)?

    For the ice skater problem, why did we use conservation of momentum and not conservation of the kinetic energy?

    For the last problem, 10 cm for the radius is .1 m not .01 m. This changes the answer. Correct me if i'm wrong!

      The way that he solved it, the radius had no affect on his answer. If you were to solve this using the k=rotational kinematics, you would have had a different answer. Just be cautious!
