Hypothesis: I think the marble will land about 13 and a half away from the table.
2 Vernier Photogates
A Vernier LabQuest mini
The procedure for this lab was simple, roll a marble down a ramp through two recording gates, then either catch the marble before it hit the ground or let it fall and record where it landed. To begin with, after everything had been set up we started the lab. What we had to do was roll the marble down the ramp 9 times, then see is those we almost the same and lucky for us they were. Then we needed to figure out the time of flight for the marble and the horizontal displacement. Lastly we had to roll the marble down the ramp a few times to see if our hypothesis was correct.
|Maximum velocity||0.704 m/s|
|Minimum velocity||0.611 m/s|
|Average velocity||0.645 m/s|
|Table Height||0.806 m|
|Predicted impact point||0.305 m|
|Minimum impact point distance||0.194 m|
|Maximum impact point distance||0.278 m|
|Actual impact point distance||0.25 m|
We found out that our hypothesis was incorrect, close, but still incorrect. We thought the ball would land at about 13 and a half inches, but it landed around 9 meters almost every time. To find out the impact point we used inches then calculated that into meters.
