The video group finishes up their discussion about the different pressures caused by a tennis shoe and a stiletto.

UPC A1 Video Clip 3: Video group working on Summarizing Question #4

The group is trying to use the equation, pressure = force/area, to decide which box wall has the greater force, and they agree that the wall in Box B has more force.

UPC A1 Video Clip 4: Video group continues to work on Summarizing Question #4

After Rebecca initially agrees with Emily that Box B (larger areas) has the greater force, she then questions the result, thinking that the smaller area would have more force. She seems to be confusing pressure and force.

UPC A1 Video Clip 5: Video group discusses Summarizing Question #4 with the instructor

This is a long video clip. The group discusses their reasoning with the instructor and why they are confused. They say that the 'math' tells them that the force on the wall in Box A is smaller, but an earlier statement in the printed materials says that 'pressure is greater when the force is applied over a smaller area.' The instructor makes a few attempts to help them think about the situation in appropriate ways.
