It's All Uphill Lab

Here is a video of me explaining the lab in front of the class:

3:11

Here is that data table. The force is the force needed to pull the cart at a constant speed up the ramp (with the force scale parallel to the ramp), and the distance is the length of the ramp from the table to the top of whatever object you have placed the ramp against. The force x distance column is just that, multiply the force ties the distance.

The questions to answer are:

1. What is the relationship between force and distance?

2. What is up with force times distance? (Is it possible that they are all the same??)
