Todays Agenda: Pass back papers Review Quiz Review Simulation Work energy theorem sample problem homework

To begin class, Mr. Manning returned a few papers and daily questions that we had completed the this week. One of these papers was the pop quiz that was taken the previous day. It was on the Conservation of Energy, and was worth a total of 7.5 points. Another grade that was handed back was the I Wasn't Speeding Activity, which was out of eighteen points and can be gotten from Mr. Manning if you missed class. The simulation packet that Mr. Manning gave us deals with work, Kinetic energy, Potential Energy, and total energy. He played the simulations on the smart board for us and explained how the answers could be found.Also at the beginning of class he had us pick up two packets. The first one was titled Work, energy, Conservative Forces, and non conservative forces notes (pgs 25-27). This worksheet teaches us about the work energy theorem, and work which is done either conservatively or non conservatively. Then, he showed us a sample problem on page 27 that he helped us solve. The answer is 11.7 meters per second, and if you are having trouble solving this problem, just ask Mr. Manning for help; he explained it thoroughly. The second packet that was given to us was titled Solving Problems Using Energy Concepts (28-30). This packet had five different problems which had us find the work done on objuects, speed, kinetic energy, and and the velocity in different situations. He gave us the rest of class today to work on these problems.
