Concepts Conveyed:

Instructions / Notes:

Set up platform and make sure is level
Clamp on the pulley to one end of the track using pulley’s built in clamp
Tie one end of the string to the cart and the other end to the mass holder - tie the string through the slit in the mass holde
Adjust the cart so it is at the back of the track and place the string on the pulley
Add different weights to mass holder and observe differences in speed of pulley
Can also place weights on the cart itself

Demo Staff:

Upon request - Send information to PASCO software on laptop to see speed differences

Open PASCO software on demo lab laptop and go to hardware set up tab
Connect cart to laptop through bluetooth or micro-USB cable (NOTE: Cart needs to be charged and on in order to use bluetooth)
Go to sensor data and click play
Velocity information from cart will be visible - can also test with different modes in PASCO software but cart sensors are not the most accurate
