  1. LEARNING GOALS: • Express and interpret relationships symbolically in accordance with accepted theories to make predictions and solve problems mathematically, including problems requiring proportional reasoning and graphical vector addition. 09 -23- 11 • WARM-UP: • HOMEWORK CHECK • Place on your desk: • *Calculator • *Orange homework chart • *Merrily We Roll Along Lab • 1) What force on earth causes falling objects fall downward? • 2) True or False: The less steep the incline, the smaller the acceleration. Agenda • Warm-Up 5 min • Lab + Graph Due! • Test Review Handout • Free Fall Acc. Notes 20 min • Formula Sheet 5 min • Free Fall Video 10 min • Free Fall Acc. Worksheet 30 min • Review Sheet 20 min gravity True HOMEWORK DUE: Merrily we Roll Along Lab

  2. Review Quiz Multiple Choice

  3. Free Fall • Why does an object fall to the ground when dropped? GRAVITY Gravity pulls objects towards the Earth at an acceleration9.8 meters/sec/sec (m/s2).

  4. Free Fall: How Fast Elapsed time– the time that has passed since the beginning of the fall. In free fall, an object accelerates at a rate of 10 m per second every second

  5. Free Fall: How Fast • To calculate velocity in free fall: velocity = acceleration X time or v=gt Remember: g= acceleration due to gravity

  6. Free Fall: How Far • How fast something falls is different from how far it has fallen

  7. Free-Fall: How Far? • To calculate distance fallen: distance=1/2g X time2 or d=1/2gt2

  8. Elephant VS Feather • With no other resistance, they both fall with the SAME ACCELERATION: 10 m/sec/sec

  9. But we all know the elephant would land first. Why? Answer: AIR RESISTANCE Air resistance alters the motion of falling objects by adding additional forces.
