Lab 7 Concussions
-
Goals
-
The goal of this experiment is to experiment with physical analysis of collisions with real-
life problems and compare the impulse from the collision data with and without a helmet.
Procedure
-
For part I, we set up the force sensor at the end of the elevated track and took the helmet off the head attached to the force sensor. We started the cart at 40 cm, released it, recorded the data with a force vs. time graph, and found the impulse with the graph. We did three trials of this. We did three more trials of this with the helmet on. Error and Precautions
-
Possible error is not zeroing the force sensor, causing incorrect data to occur. -
Another possible error is the angle of the track, or the track being elevated too high. Results
