Today we talked about integrating the acceleration function to get the velocity function, and integrating the velocity function to get position. We're doing the same thing we did with graphs - the area under the acceleration graph gives us the change in velocity, and the area under the velocity graph gives us displacement. Homework was a practice worksheet. Here are the solutions (note that there is an error in #10 on the derivative side, so if you have a different answer, you are probably correct.)

Today we talked about how to use calculus to find velocity and acceleration from a given position function. We learned simple rules to find the derivatives of polynomial functions. Homework was a practice worksheet (which almost everybody finished in class!)
Today we looked at various position-time and velocity-time graphs, and answered questions about them. Then we continued working on the free fall problems from last week (the really difficult ones). You have 6 additional book problems to complete for tomorrow - p. 66 #15-18, 26, 27, 28. Make sure you finish the book problems for tomorrow, it will be collected. Solutions are available here. If you are struggling with the free fall worksheet, keep working on it, and make sure you find time to get some help. I won't collect the free fall worksheet problems until Thursday.
I think I've found all of the mistakes in the answer key! The answers should (hopefully) be correct now. Let me know if you see a mistake that I have missed.
Quiz tomorrow on interpreting graphs, and constant acceleration problems. The quiz will not include free fall. This worksheet was more challenging than I originally thought. Do as many as you can. We will have a work day tomorrow to go over these problems and practice more. The answers to the first few problems (I am still working on the key) are:
Today we talked about free fall and practiced solving problems with free fall. Homework is to finish the worksheet we started in class. Due tomorrow.
Please finish yesterday's assignment for tomorrow! Solutions are available here if you would like to check your answers.
Today we analyzed a velocity-time graph and were able to determine the object's average velocity over different intervals, it's displacement in a given interval, and its average acceleration. Then we began working on problems from the book. Homework is p. 64 CQ #5, 7 and p. 65 E #6-14. Try the first 6 problems on your own. We will have a work day tomorrow so we can complete the problems together. Solutions will be posted tomorrow after we talk about these problems in class.
Today we analyzed the data from the marble lab and derived our 4 kinematics equations for constant acceleration. We began working on problems in class. If you did not complete through problem 10, you should finish them for homework. Solutions will be posted shortly.
Today you gathered position vs. time data for a marble rolling down an inclined track. Make sure to graph your data for class tomorrow. We are going to use the information to derive our kinematics equations.

REMINDERs:Chapter 2 test retake is Monday 10/15. You can take the retest either before school or after school, but you must complete all of the Chapter 2 homework (75% completion on each assignment) to be eligible for a retake!
