Centripetal Force Accessory

Model No. ME-8089

6

®

Note: 

Always lay down the cable 

before

 adding the mass. 

14. 

Add a mass over the cable on the sliding mass holder; then tightly 

screw on the knurled nut to hold the mass in place (Figure 4).  

15. 

Add a mass to the fixed mass holder and use a knurled nut to hold 

the mass in place.  (

WARNING

: Keep the thumbscrews tight or 

the mass holder will slide off during the rotation.).

16. 

Move both the fixed and sliding mass holders the same distance 

from the center on the platform (You can choose any arbitrary 
radius). 

17. 

Plug the Force Sensor into a  a 

PASPORT or 

ScienceWorkshop

 

computer interface.

CAUTION:

 Keep all cords away 

from the rotating arm.  The rotating 
arm must be free to move 360 
degrees without hitting any objects 
in its path.

WARNING

: Do not stand 

next to rotating arm or look at the 
rotating arm at eye level.  To avoid 
possible injury from the rotating 
arm hitting the body, keep at least 1 
foot distance from the rotating arm. 

18. 

Open the appropriate DataStudio file on the experiment setup disk.

19. 

Launch DataStudio and click the 

Start

 button to begin collecting data.

Note:

 To calibrate the 

ScienceWorkshop Force 
Sensor, follow the 
instructions provided in 
the documentation 
included with your 
Force Sensor or in the 
DataStudio online help.  
Calibration of the 
PASPORT Force Sensor 
is not required.  
However, you can tare 
the PASPORT Force 
Sensor by pressing the 

Zero

 button without any 

weight attached.

Note:

 PASCO’s PASPORT 

Force Sensor (PS-2104) 
requires a PASPORT 
interface; PASCO’s 
ScienceWorkshop Force 
Sensor (CI-6746) requires 
a ScienceWorkshop 
interface.

Note:

 DataStudio setup 

instructions (for either 
PASPORT or Science-
Workshop sensors) are 
available in Appendix A
