Date: September 24, 2013HW: 2.1 PTG #1-6, Due Thursday • Do Now: • Copy LO and SC • Agenda: • Do Now • Learning Objectives • Success Criteria • Investigate • Active Physics Plus • Physics Talk • PTG #1-6, pg. 143 • Learning Objective: • Explain why objects keep moving after the force on them ceases to act • Success Criteria: • Describe Galileo’s law of inertia • Apply Newton’s 1st law of motion • Recognize inertial mass as a physical property of matter

  3. Do Now: • Read Investigate #1-5 pg. 133 • Agenda: • Do Now • Learning Objectives • Success Criteria • Investigate • Active Physics Plus • Physics Talk • PTG #1-6, pg. 143 • Learning Objective: • Describe how an object’s velocity depends on the frame of reference • Success Criteria: • Use examples to demonstrate that speed is always relative to some other object • Explain that the speed of an object depends on the reference frame from which it is being observed

  7. Do Now • A train is traveling at 30 m/s. A passenger on the train tosses a ball up in the air and it comes right back to him. A bystander sees the passenger from road next to the tracks the toss the ball through the window of the train. How fast is the ball moving to the bystander?
