Topic: Terminal velocity

Problem Statement: A parachute falling in air eventually moves with a velocity known as a terminal velocity. A toy rocket contains a small parachute which is ejected from the rocket a short time after launching. The designer of the rocket wishes to know how the terminal velocity of the parachute is affected by the diameter of the canopy and the load which it carries

Design a laboratory experiment to investigate how the terminal velocity of the parachute depends upon the load which it carries and the diameter of the canopy. In your account you should pay particular attention to the following:

The method by which the diameter of the canopy and the terminal velocity are to be measured.

The control of variables

Any important precautions you would take which may improve the accuracy of your experiment.
