Today we graded the review worksheet; I will hand them back tomorrow so you can study for.....
Answers will be added on Friday so you can check back here after you try problems out.
Also today we explored a bit with friction involving different items and practiced using spring scales. We came up with some different independent variables which MIGHT affect friction between surfaces, such as: surface types, force pushing forces together (like weight), wetness, oil, surface area, speed an object's moving, etc. Tomorrow we'll run a lab to test these variables and see which ones do affect friction.
Thursday's homework: Read p.p.83-86; work problems #1-7 on p.86.
Friday we will work with air resistance, working with problems, videos, and demonstrations.
