I just wrote a problem where students had to convert 10 m/s^2 into mph/s, and then figure out how fast a car would be moving if it were to accelerate at the same rate of g for 3 seconds. <br /><br />I also like just talking about forces in terms of lbs. <br /><br />I think the trouble with mph/s and lbs is when we get to Newton's laws-- we'd need to define some new mass unit as the mass that would accelerate at 1 mph/s with 1 lb force.Brianhttps://www.blogger.com/profile/06289013669698459078noreply@blogger.comtag:blogger.com,1999:blog-7356300930740320331.post-59739807723450001612011-04-12T17:01:01.669-07:002011-04-12T17:01:01.669-07:00I like these examples, especially how you've t...I like these examples, especially how you've tied it to the queen (v_avg for those who aren't following along ;)<br /><br />I've posted this before but I really like g=22mph/s for the acceleration due to gravity. Of course it only works in backwards countries like the U.S. but, still, I think it gets to the essence of what you're posting here.<br /><br />Keep up the good work, Brian, I'm really curious about the seven of hearts.Andy Rundquisthttps://www.blogger.com/profile/04900696452285397726noreply@blogger.com
