Re: [Phys-l] Torque, angular momentum, dissipation, etc. in an advert.



To maintain the exagerated speed against air resistance attributed to Ohno in this ad, superhuman forces are needed which could easily move an entire arena. This is a humorous ad that is a great jumping off point for class discussions. Spouting dogma would just ruin any value the immediacy of the Olympics would give to the video.

The worst thing the ad does is to reinforce the common misconception that force is related directly to speed rather than to acceleration. This is just the rotational analog of that misconception.
