- Homework Statement:
- Carry out an investigation in to the relationship between the mass of an object (m) and the distance from the fulcrum (d) at which it will cause the plank to tip.

- Relevant Equations:
- You will use a ruler to model the plank and a pile of quarters (6) to model the mass of the cyclist

I kind of know what to do but not really. My first step is data gathering, so it says to place your ruler on a flat surface (i.e a table) then place a coin on the tipping point then add more coins and move them to find the new tipping point. My question is in my data table I need to make what are the values I need to collect? distance (d) and mass(m) the mass in the independent variable correct? and distance is the dependant? Also, how should I set up my data gathering table?
