This project investigates how the shape and mass of an object affect its terminal velocity. By using coffee filters, students can analyze the time it takes to fall from various heights. The experiment encourages understanding of forces and motion.
The time taken for coffee filters to reach the ground will increase with height due to the effects of air resistance.

Measure and mark heights of 1, 2, and 3 meters.
Drop a coffee filter from the 1-meter mark and start the stopwatch.
Record the time taken for the filter to reach the ground.
Repeat the drop two more times and calculate the average time.
Repeat steps 2-4 for the 2-meter and 3-meter marks.
Ensure that drops are done in similar weather conditions.
Compare the times across different heights.
Analyze the effect of height on terminal velocity.
The time taken for the coffee filters to reach the ground will increase with height, demonstrating terminal velocity.

Ensure the drop area is clear of obstacles. Use a soft surface for landing.
Use graphs to illustrate time vs. height.
Include a video of the drop experiment.
Explain the concept of terminal velocity in simple terms.
Discuss real-world applications of terminal velocity.
Terminal velocity is the constant speed that an object eventually reaches when falling through a fluid, such as air.
Coffee filters have a large surface area relative to their weight, which increases air resistance.
Yes, but ensure they have similar weights or shapes to accurately compare results.
