How Do Static and Kinetic Friction Compare in Physics Experiments?

[jellybeansies]

1. Comment on the difference (if any) between the slopes of the lines of best fit and the tangents of the angles of incline.
In my data i got that the static friction slope was 4N/kg and the kinetic was 2.2N/kg. and i think that we're supposed to divide that number by the gravitaional field intesity of 9.8 m/s [down] (0.408-static) and (0.488-kinetic) then compare it to the tan which i got 0.488-static and 0.344 for kinetic and when i calculated percent difference i got 18%(static) and 42%(kinetic).
So, what comments should i say?

Homework Equations

3. I think that the static is bigger because it takes more force because of the bonded ground to the block that we made slide down a plank of wood. and then when its moving its easier so the kinetic is easier. =(

sorrrry it was my first time.
i kind of messed up the stuff.
