- Seems to work better with the filter dropping down from the detector.
- Best results when you let the filter drop as far as possible.
Learning Goal: To use Newton's Laws of motion to predict the behavior of objects' motion.
Today:Coffee Filter Skydiver Lab
- Q1: How does the velocity and acceleration of a falling object change over time when under the dual influence of gravity and air resistance?
- Q2: What effect does varying mass have upon the terminal velocity value of an object which is falling under the dual influence of gravity and air resistance?
- Materials Required: Coffee filter; computer‐interfaced motion detector.
- Description of Procedure: Students drop a coffee filter and use a motion detector to capture the velocity of the filter as a function of time. Use the distance-time graph or the velocity‐time graph to accomplish the purpose of the lab.
- Once this has been done several times for a single filter, add filters one at a time and repeat. Make sure that the filters are securely fit into each other.
- Your conclusion should explain the evidence behind your answers and include FBDs of the forces acting on the filter. Your conclusion to Q2 should include a graph.
