D.4 Materials: -­‐1 trolley that will be accelerated -­‐1 string to connect the trolley and

the weights (ca. 2m) -­‐1 set of weights that will accelerate the trolley (up to 5N) -­‐1 a.m. to measure the acceleration Smart ^

(including all pieces)

D.1 Aim of Experiment:

^Trolley

The aim of this experiment is to test Sir Isaac Newton’s second law of motion F=ma (1). We will be testing this by accelerating a test trolley (Trolley’s weight: 667.29g) attached to a weight hanging off a table over an acceleration meter (smart pulley). The a.m. (2) is connected to a device that measures and graphs any de/acceleration that a cured. We will plot the results and determine our final data by the plots

-­‐1 long testing plank where the trolley can accelerate on -­‐1 table, or other type of elevation so that the weight can fall somewhere -­‐1 paper and pencil / computer for plotting results

D.5 Method:

D.2 Hypothesis: m a

I think that the higher the force the faster the acceleration. Since F=ma and a=F/m
