Create a lab experiment where you can find the friction constant of the tissue box with the floor (no surface tilting or accelerometer allowed).
- Various Weights
- Tissue Box
- spring scales
So since I couldn't vary the inclination of the floor or use a accelerometer and advance devices, came up with the quickest thing I could do in the time I had. I pulled the tissue box on the floor using a constant force eg 400g and time how long it took to go 1 meter. So I have velocity and force. And I did the same thing with different weights.
I was thinking at the time I could use the .5mv2 to get the energy then use the F=Ed where d is 1 meter, to get Force and use that and the F=muN to get the friction coefficient.
So my questions:
1. Is that allowed?
2. I used different horizontal forces to pull each tissue box weight for example I pulled the 700g tissue box with a force of 200g and got a velocity of .199 m/s and I pulled the 1200g tissue box with a force of 400g with a velocity of 0.151285930408472 how do I convert them so they are the same?
