Procedure For Data Collection
1. Weigh the ball you are using and record mass.
Connect the CBR to your graphing calc.
2.
Check under
APPLICATIONS
to see if your calc has the
ranger
program.
If it does, skip step 3.
3.
Press
2
nd
Link > Enter > Receive
Open the pivoting head of the CBR and press the number
that corresponds to the model number of your calculator
4.
Press
program
, choose
ranger
and press
enter
5.
From the
main menu
choose
applications
and select
meters
6.
From the
applications
menu choose
ball
bounce
and follow calculators instruction
7. Hold the CBR at least .5 meters above the ball
8.
Press
enter
(this triggers the ranger program).
9.
Press
trigger
on the CBR and when the green light begins flashing release the ball. (You may
move the CBR side to side to follow the ball, but be sure NOT to change the height)
10.
Press
enter
and the graph of
distance vs. time
will appear on the screen. If the graph does not
appear completely smooth, repeat the data collection procedure until you have accomplished
your goal.
When the first several consecutive bounces look good, you may use the
plottools
option to
select
the
domain
you wish to analyze.
11.
*****
Use only the data for the initial fall, plus exactly 2 more complete bounces
.*****
12.Exit the program to perform the following calculations.
(Once you exit, do not run ranger)
Procedure for Creating Graphs
1.
When you exit the program time, distance and velocity are automatically plug into lists L
1
, L
2
and L
3
respectively.
2.
Plug potential energy into L
4
, do this using the following equation
mg L
2
L
4
(L
2
is the data for
height and the reason this works is because potential energy is equal to
mgh
)
3.
Plug kinetic energy into L
5
, do this using the following equation
1/2m L
3
2
L
5
(L
3
is the data for
velocity and the reason this works is because kinetic energy is equal to 1/2mv
2
)
4.
Plug total energy into L
6
, do this using the following equation L
4
+ L
5
L
6
(L
4
and L
5
are the data
for P.E. and K.E. respectively and total energy is equal to kinetic energy plus potential energy.)
In the space below, accurately draw the height vs. time (L
1
, L
2
) and velocity vs. time (L
1
, L
3
)
graphs; pay attention to their shapes and ESPECIALLY the slopes of each curve.
