Friday is Fun Day!

B Block went over their simple machine homework and then reviewed for Tuesday's exam. On Monday, you'll work on a lab that investigates levers and pulleys that will let you wok with the concepts of mechanical advantage and efficiency.  C Block conducted that lab today and found that distance is the key to multiplying your effort force.  Apply a force through a large distance and you use a relatively small force to get a job done.  F Block conducted only the lever potion o that lab today, but e main concepts were still emphasized (albeit without the fun of working with pulleys and pulley systems).  Poo old' E Block spent the period getting some problem-solving practice for Newton's Second Law for rotation, conservation of angular momentum and conservation of energy.  I'll get some videos up this weekend to give you some additional guidance, but feel free to email me if you have a question.

See folks Monday!
