Investigating Leonardo Da Vinci's claims on Frictional Force
Leonardo Da Vinci (1452-1519) stated the three basic laws of friction 200 years before Newton even defined what force is. Da Vinci simply stated that:
1) if the load of an object is doubled, its friction between the load & surface in contact with also be doubled
2) The amount of friction between two surfaces depends on the type of surface
3) the size of surface areas in contact have no effect on friction.
We used the pulley system and a series of weights to measure the amount of frictional forces between the surfaces in contact. It is also possible to use the spring balance to do so.
Something to think about - Which method is better and why?
