2-11

Today in physics we had a shorter period because of the PSSA's and only had class for 30 minutes or so. Since the seniors had class all week they continued working on the 'Total Mechanical Energy' lab while mr manning got the rest of us caught up by giving us a brief run down of the lab. We recieved the 'Total Mechanical Energy' lab which was worth 10 points (pgs 16 and 17) and the 'I Wasn't Speeding' activity 18 points ( page 5b). With the lab we have to work with potential energy (Ep=M times G times H) and Kinetic Energy (Ek=1/2 mass times velocity squared) by measuring the height of a ramp from the front of the little car and we use kinematics to find out the distance traveled and whatnot. The 'I wasn't speeding' activity is basically a problem analysis and we have to adress all aspects of the problem and show how these problems relate to the application while showing creativity. That worksheet is due on tuesday. Well that was physics today, peace.
