QUIZ TOMORROW
Drawing X vs. T, V vs. T, A vs. T,
and Motion Maps for Constant
Acceleration Motion
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
FREE-FALL: PICKET FENCE
Description:
You will be dropping a
“Picket Fence” through a Photo Gate
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.
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.
FREE-FALL: BASKETBALL
Description:
You will be tossing a
basketball up above a motion
detector
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
FREE-FALL: BASKETBALL
Record
the graph of X vs. T, V vs. T,
and A vs. T
Record
 Note:
Fill
the value of acceleration
Might have to find the mean
in the table
FAN CART: BLUE FANS
Description:
You will be measuring the
motion of the cart as it moves away,
then comes back to the sensor
FAN CART: BLUE FANS
DO
e
Hit
NOW: Make your predictions. Do part
“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
FAN CART: BLUE FANS
Answer
parts a-d, and f-j
FAN CART: RED FANS
Description:
You will be measuring the
motion of the cart as it goes towards,
then away from the sensor
FAN CART: RED FANS
DO

Hit
NOW: Make your predictions. Do parts
“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
