Week 10 Reflection

This week we learned more about force pairs and how to draw force diagrams with component forces and how to make a quantitative force diagram. 

To demonstrate force pairs, we used the force plates.  We made two students hold and push against each other with the plates.  Then we would check the graph.  They would always be the same amount of force pushing against each other.  Even when we had one student in a rolly chair and another student on their feet and push hard enough to make the chair roll.  It didn't matter because the same amount of force would push back on the opposing force plate.

We learned how to draw more complex force diagrams such as adding in strings holding up an object, objects falling with or without air resistance, etc.  An example would be drawing a force diagram for a freefalling skydiver with no parachute with no air resistance acting upon the person. You would draw an arrow pointing straight down because gravity is the only thing acting upon the skydiver.

We also learned about quantitative force diagrams.  They are not to much different than regular force diagrams other than you need to label how much force is acting upon in object, usually in newtons.

This week I think I did pretty well in participating and listening well.  I think that I get most of the stuff that is being taught to us and I improved on doing the force diagrams right.
