Computer Intensive Physics Robert G. Fuller

Portugal Conference

March 6, 199820 University of Nebraska - Lincoln

We asked the students to explore how these two different things fall. Then you work with them to invent, what the necessary physics concepts are when you have to talk about gravity.

You have the students draw a free body diagram of all the forces on a falling coffee filter and they have to talk about air resistance (Figure 34). You can send them to the "InfoMall" to look for some references of about air resistance.

One of the things we provided, in addition to, was a video of a person holding up a coffee filter in front of a marker on the wall where there is a clock running (See Figure 35). The students can play this video sequence. They can read the time of the coffee filter fall from the clock and also find the location of the filter as it falls down.
