# Air Resistance Lab

Materials Available:

• Coffee Filters (6 per group)
• Meter Sticks
• Tape

What to find:

Determine a general mathematical relationship between air resistance (drag) and terminal velocity. You must drop coffee filters flat bottom down.

• How soon does terminal velocity appear to take place?
• What forces are acting at terminal velocity? Diagram and write a net force equation.
• How will you relate the coffee filters to air resistance?
• What will you do with the data to determine the relationship? (Graph!)

Data Analysis

1. Data Table, clearly labeled.
2. Multiple trials (Minimum of 5 for each variable)
3. Graphically determine the relationship between air resistance and terminal velocity. Fully show any calculations you do.
4. Give a general mathematical model for this relationship.
