Presentation Transcript

  1. Linear Kinematics - Free Fall • Contents: • Graph • Definition of and Terminal velocity

  2. Time A B C 0 m/s Velocity A - Free Fall - only gravity acts (a = -9.8 m/s/s) B - Transition from free fall to terminal velocity (a goes to zero) C - Terminal velocity (a = 0) (forces, vertical wind tunnels, type of object) (Demo - feather in vacuum, ping pong ball in vacuum, race twixt steel ball and pp ball)

  3. Time A B C 0 m/s Velocity Objects in free fall (region A) experience a zero g situation Demo - water bottle

  4. Demos: • Feather, Ping pong ball, Steel marble • vertical wind tunnel • terminal velocity • definition of Free Fall • Zero Gravity • gravity detector • Drop • Fling • DC-9 • filming Apollo 13 • YouTube(NASA Water Balloons in Zero G (High Quality)) • YouTube(Symphony of Spheres in Microgravity) • Show our experiments (DIME 2006)
