Busy Friday

Yesterday was a busy day for all concerned. Physical Science completed the material for their Work and Energy unit with a discussion of efficiency. Have those worksheets completed by Monday. Remember, when calculating efficiency it might be necessary for first calculate the work inpur or output or the enegy provided to or delivered by the machine. Keep your wits about you and think through the problem before trying to plug numbers into a formula. Monday will be review day and I'll have a couple of practice tests available for you to work on. Physics delved into the area of moment of inertia. No, you don't have to memorize the moment of inertia formulas, but you should read a problem closely and make a decision about which common shape the object in question most resembles in order to choose the correct formula to use for your calculations. This will be especially important as we move into using moment of inertia to calculate angular momentum, angular acceleration and rotational kinetic energy. Honors Physics had an overview of simple machines, mechanical advantage and efficiency. Monday is also review day for you guys, so come prepared with questions. After Tuesday's exam, we move into how forces behave with fluids.
