**RipStik change in momentum is force**

Based on the providing a transition from coverage of momentum on Friday , I attempted to show that the external force would be equal to the change in momentum. The layout was similar to attempts to measure this from a few terms ago, but with some changes. I...

**An exploration of marble momentum without the word momentum**

As noted in an earlier blog, over the years I have gradually developed better transitions and connections between the aspects of motion in the physical science class. Linear motion often yields a slight amount of non-linear curvature. Week three specificall...

This term the walk and talk benefited from the healing plants of Paies handout I prepared spring 2018. Leveling work prevented going down to the three plants near the intersection, the usual start for this walk. Volkameria inermis. Chuuk (lagoon): apuoch, a...

**RipStik height versus velocity**

In the spring of 2018 presentations on arc equations eliminated this height versus velocity exercise in SC 130 Physical Science. Fall 2018 the students had all arrived at the same equation very quickly on the previous Friday, in stark contrast to the prior ...

**Seedless vascular plant walk and talk**

This term the area around the mango trees is undergoing leveling, ruling out starting the walk on an eastward arc into that area as I have done the past few terms. On the other end of campus an area where I had found Macrothelypteris torresiana and Pteris t...

**Linear motion**

As per notes made January 2018 , I shifted back to using meters for the RipStik linear motion exercise to simplify Desmos data entry. Prior to class I measured out a 30 meter run with timing marks every three meters. I also set up a Desmos table with the di...
