COLLISION CARTS AND FORCE SENSORS


APPARATUS
track 113B
two collision carts 101-05-G1
two force sensors, set to 50 N scale 101-05-B2
500 g masses 101-05-G3
string 202-02-C3
laptop and ULI
113


DESCRIPTION
Use the force sensors to show that when the carts interact, the forces are equal in magnitude and opposite in direction.  There are different attachments for the force sensors for elastic or inelastic collisions, or for pulling or pushing.  Add masses to one to show that relative mass is not a factor.
 
NOTES
 
Open "third law" experiment file.  Set force sensors to their 50 N scales and calibrate.  Secure sensors to carts and zero them.

Use rubber stopper attachment for elastic collisions, clay for inelastic collisions, and hooks for pulling.
