1. “The final push”

2. Welcome, what to expect this semester  AP Physics Review Assessment  Momentum introduction  Homework: Holt Momentum homework #1

3. What to bring to class 1.Giancoli book 2.Homework completed and stamp sheet 3.Well rested brain ready to learn 4.Calculator At Home (new students will need to get these) 1.Homework completed so that you are ready for class 2.Calculator

4. FEB 3, 2014 Welcome to Semester 2, what we will be studying Assessment for Reviewing last semester Collision on PHET—computer room Notes on Conservation of motion and collisions Today’s vocabulary: Linear momentum Conservation of momentum Homework: Do homework sheet #1/ Practice assignments due Friday Kinematics review due next Tuesday Learning Target: Be able to describe Conservation of momentum. Question of the day (turn to a neighbor and discuss): What are three physics concepts you learned last semester?

5. END OF CLASS-SHOW WORK AND UNITS FOR CREDIT A 2250 kg. Pick up trruck has a velocity of 25m/s to the east what is the momentum of the truck? P=mv P=56000 kgm/s to the east
