Impulse and the change of momentum conservation

Set up the equirement as shown.

1.Level the track.
2.Calibrate the force sensor.
3.Turn force sensor horizontal and zero sensor.
4.motion sensor
Measured the mass of the cart is 0.434kg. The the mass of the block is 0.084kg.




Compare mv*=-0.764 N*s and the intergration of the force by time which is -0.6706 N*s.
those nubmers are colsed.

Elstic collsion.
Add a block on the cart and redo this experiment.
Compare mv*=-0.303 N*s and the intergration of the force by time which is -0.2723 N*s.
those nubmers are colsed.
Use a plasticene instead of the red car so that change it to be a inelstic cllosion.


Compare mv*=-0.203 N*s and the intergration of the force by time which is -0.235 N*s.
those nubmers are colsed.

Through this experiment, we can conform the impluse is the change of the mementum.
