A brand new semester!

• Mon 2/4:  Hand back final exams, check them over, and recollect.  Conservation of Momentum.  Problems 9-16 on Chapter 6 problems due Thurs/Fri.
• Tues/Wed 2/5-2/6:  Conservation of Momentum w/ objects going opposite directions.  Ballistic Pendulum Quick Lab done one table at a time.  For those who finish early, go to Collision Lab Simulation on my website, do 5 different trials recording mass 1, velocity 1 initial, velocity 2 initial, mass 2, velocity 2 initial, and velocity 2 final.  You need to record the initial velocities before you press  "Play" then record the final velocities.  Finally, for each case, calculate the momentums, and see if momentum is conserved.
• Thurs/Friday 2/7-2/8:  Check off problems 9-16 and go over.  Turn in Ballistic Pendulum Lab (neat, organized data table, uncertainty of height, and calculations for speed of ball and pendulum arm together, and speed of ball before it hit pendulum arm).  Elastic and inelastic collisions.  Newton's Cradle.  Explain centripetal acceleration and go over the equations for centripetal acceleration and centripetal force.  Do problems 1-5 on 7+8 problems for Mon/Tues.
• Mon/Tues 2/11-2/12:  Check off problems 1-5 and go over.  Circular Motion Lab.  Universal Law of Gravitation.  Do problems 1-8 on 7+8 Worksheet for Wed/Thurs.
