Reminder: Turn in your Frictionless Car Lab report if you haven’t already.

ANNOUNCEMENTS

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 the value of acceleration Note: Might have to find the mean

Fill 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 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

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 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

FAN CART: RED FANS

Answer parts a-d, and f-j
