The Fall of a Coffee Filter

Aim:

As a basket-type coffee filter falls, it tends to fall straight down and not flip over.  This allows us to design a lab with several interesting variations on the independent and dependent variables.  

You very recently were told to drop coffee filters and change several different variables as you dropped the filters.  You also measured several different responding variables.  Based on your brief exposure to the wonders of falling coffee filters, you will design a lab that could be performed by another student in a normal physics class.  

Apparatus:

Basket-type coffee filters and any other equipment you think you might need.

Design:

or –cv2. At terminal velocity, the downward force is equal to the upward force, so mg = –bv or

mg = –cv2, depending on whether the drag force follows the first or second relationship. In either case, since g and b or c are constants, the terminal velocity is affected by the mass of the object.

Variables:

Independent: Mass of coffee filter

Dependent: Time that takes coffee filter to become  

                  terminal velocity

Control:

  • Gravity
  • Height
  • Person who drops the coffee filter/ starts and stop the motion sensor
  • Location
  • Condition of the class room
  • Same motion sensor

Materials:

  • meter stick
  • packet of nine coffee filters
  • motion sensor
  • laptop
  • electronic balance for weighing mass.

Experiment Setup:

Procedure:

  1. The motion sensor should be connected with the laptop and then placed on the floor and be ready for measuring the velocity.

pan class="c5">Remove one coffee filter from the packet leaving it as 8 coffee filters. Weight it again, record the mass and place it above the motion sensor. Repeat procedure 4 and 5Do the same procedures till the coffee filters inside the packet remains one.After noting down all the results, take the average time for trials for the same weight and then compare the time to see whether time is longer for the coffee filters if the mass is high.Use this data to write a good lab report.

    The temperature of the test environment will also remain constant, which should help maintain a consistent amount of air resistance that the paper will encounter. The vertical displacement will remain constant at 520.0cm because it will help maintain the time of descent to surface area ratio at a constant throughout

    m = 35.254 �0.059 Hz2kg-1 (total absolute error) Therefore, we can thus conclude that there was yet again a high amount of uncertainty and it will be calculated through the percent error. The systematic error still exists, however random errors are not as frequent in this experiment. Conclusion The graphical analysis states all the basic trends attained from the graph.

  2. Investigate the factors affecting the period of a double string pendulum

    Thus only the formulas between the variables change but the general relationship (inversely or directly proportional) do not change for any different bars. The general explanation of this phenomenon is possibly that as I increase the distance between the two strings whilst keeping the other factors constant and controlled, I increase the tension in the strings.
