The purpose of this lab was to recognize the relationship between the amount of force used to pull something and the slop that it was being pulled on. In this experiment we pulled a a small cart up a ramp starting with a moderate to minimal slope and then gradually increased the steepness of the slope each trial. While pulling the cart, we had an electro magnetic pro measuring the amount of force it took to carry the cart up the slope. We also learned the equation W=FxD, which perfectly explains the relationship between the amount of work that is put into pulling the cart up the ramp, and the distance.
Data:
Trial 1: Distance= 1.5 m
Force= .767 N
Work= 1.15 J
Trial 2:
Distance= .85 m
Force= 1.822 N
Work= 1.54 J
Trial 3:
Distance= .55 m
Force= 3.9 N
Work= 2.15 J
Connection:
A connection that you can make from this lab to the real world can be found on ramps for wheelchairs and in the pyramids of Egypt. The ramps for wheelchairs are at the perfect slope because they do not require much effort to go up one and they are not too long either. The pyramid's ramps had the same properties as the ramps used for wheelchairs, they were moderate enough that you could pull or push something up them but at the same time they required very little distance.
