1. CONSTANT ACCELERATION MOTION MEDLEY MINI LAB GRAB A MINI-LAB WS from the front Reminder: Turn in your Frictionless Car Lab report if you haven’t already.

2. ANNOUNCEMENTS QUIZ TOMORROW Drawing X vs. T, V vs. T, A vs. T, and Motion Maps for Constant Acceleration Motion

3. MINI-LAB MEDLEY  There are 4 different activities to do:  Free-fall: Picket Fence (Lab stations 4, 5)  Free-fall: Basketball (Lab Stations 1,3)  Fan Cart: Blue Fans (Lab Stations 8,9)  Fan Cart: Red Fans (Lab Stations 6,7)  YOU WILL HAVE 15 MINUTES TO DO EACH STATION

4. FREE-FALL: PICKET FENCE  Description: You will be dropping a “Picket Fence” through a Photo Gate

5. FREE-FALL: PICKET FENCE  Hit “Collect”  Drop the Picket Fence through the PhotoGate  Record the positions and associated times (i.e. the time at that particular position)  Calculate the ∆t and ∆x for each interval and then velocity  Note: This will probably be different than what the computer will say.

6. FREE-FALL: PICKET FENCE  Use our LoggerPro tricks to find the slope of the V vs. T graph and acceleration  Note: You might need to average the accelerations to find a good value  Select data and clicking “Stats”. Look for the mean.

7. FREE-FALL: BASKETBALL  Description: You will be tossing a basketball up above a motion detector

8. FREE-FALL: BASKETBALL  DO NOW: Make your predictions as to what the X vs. T, V vs. T, and A vs. T graph will look like.  Hit “Collect”  Toss the basketball into the air above the sensor.  It doesn’t have to be too high, as long as your graph seems smooth and consistent

9. FREE-FALL: BASKETBALL  Record the graph of X vs. T, V vs. T, and A vs. T  Record the value of acceleration  Note: Might have to find the mean  Fill in the table

10. FAN CART: BLUE FANS  Description: You will be measuring the motion of the cart as it moves away, then comes back to the sensor

11. FAN CART: BLUE FANS  DO NOW: Make your predictions. Do part e  Hit “Collect”  Give the cart a gentle push away from the motion detector.  It doesn’t have to be too hard.  Let the cart go away and come back towards the motion detector.  Stop it before it hits the motion detector

12. FAN CART: BLUE FANS  Answer parts a-d, and f-j

13. FAN CART: RED FANS  Description: You will be measuring the motion of the cart as it goes towards, then away from the sensor

14. FAN CART: RED FANS  DO NOW: Make your predictions. Do parts e  Hit “Collect”  Give the cart a gentle push towards the motion detector.  It doesn’t have to be too hard.  Let the cart go towards the motion detector then away.  Don’t let it hit the motion detector

15. FAN CART: RED FANS  Answer parts a-d, and f-j
