Hope you found the lab interesting and helpful in understanding the conservation of energy. Think about some of the things we've talked about last class, such as what are we measuring and where the energy has gone. If you have any question about the worksheet, the simulation, and/or the lab, please feel free to email me!
Here are the Plicker questions of the day:
1. Near the end of the tape, you label seven points as your reference points. How would you find the VELOCITY at the 4th point?
A.Calculate the average velocity between the 4th point and start of the free fall
B.Find the displacement between the first and seventh points and divide that by 0.1 second
C.Find the displacement between the first and seventh points and divide that by 6
D.Draw a distance-time diagram for the entire free fall.
2. How would you find the HEIGHT of the free fall?
A.Use the displacement between the fourth point and the start of the free fall as your height.
B.Use the displacement between the first and seventh point as your height.
C.Divide the displacement between the first and the seventh point by 6.
D.Divide the displacement between the fourth point and the start of the free fall by the number of dots.
Don't forget to hand in your lab reports on Thursday!
