ABSTRACT:
This experiment is about finding the value of acceleration due to gravity with the application of Newton’s Laws of Motion. This paper discusses the theory involved which was demonstrated mainly through mathematical equations. The set-up that was used was the cart and pulley experiment but using a toy crane instead of a normal cart. The independent variable (controlled variable) was the distance and the amount of weights applied to the toy crane as well as to the weight hanger. The dependent variable was time which was from the time taken of the toy crane to pass the marked starting point as well as the ending point. The trials were executed 10 times per weight increments on the hanger. There were three sets of the experiment done, for 30 g, 40 g and 50 g hanging weights. The equation to find the value of g discussed in the earlier parts of the essay was the formula to which the data collected was substituted. The value of g that was acquired from the experiment was proofed for percentage error against the theoretical value of 98.1 cms-2. The conclusion of the experiment found that the actual value of the value of g ranges from 149.4 cms-2 and 103.3 cms-2.
