Notes for the Block of Wood on the Incline

Using the acceleration of the block and hanging mass system to determine the coefficient of kinetic friction (we got it to be about 0.26-0.28 in class) and then using that to predict the acceleration for the block sliding down a steeper incline without tension.

Notes for Friction

Here's a pdf of the notes from the SMARTBored

Bob and Jane Video

Here's a video walk through of the first part of the Bob and Jane problem.

And here are some examples of P4s work on this problem...

Data for Analysis

Here's a link to everyone (that submitted data)'s data and analysis from the accelerated cart lab.  Take a look at both sheets, and see if you can ID some patterns.
Accelerated Cart Data (constant system mass version)

Accelerated Cart Data (constant unbalanced Force version)

Share Your Data and Analysis for the Lab

In order to identify the patterns for this investigation, it will be helpful if we can look at a data from a number of different groups.  To make it feasible to collaborate with students in the other periods, please enter your data and analysis tonight using one of the following links.

Window Side Groups
We purposefully changed the UnBalanced Force (aka Fu), and we took great care not change the amount of mass in the system.

Wall Side Groups
We purposefully changed the system mass, but were very careful not to change the UnBalanced Force (aka Fu).
