Homework Statement
So, we were given these instructions to find the terminal velocity reached by an object falling through the air:
Equipment: bun-case; access to balance; calipers; metre rule; stopwatch.
Instructions:
1. Record the mass of the bun-case
2. Measure with a recorded precision the dimensions of the bun-case and draw a scale diagram of it.
3. Drop the bun case from approximately 1m above the ground and observe its fall.
4. Plan a method to time the fall of the bun case as accurately as possible.
5. Time the descent of the bun-case from 1m and then in increments up to a maximum of 2m to give sufficient data for analysis.
6. Plot a graph of time against height of drop
7. Plot a graph of average speed against height of drop
8. Use these graphs to estimate the terminal velocity and give your reasoning.
But how do we do that?

The Attempt at a Solution
So, if you find the average speed (height/time) for each height at which you dropped it, eventually the average speed will plateau on the graph, equalling the terminal velocity?
Or is there a different reason? Thank you!
