Question

Students are then given strings of various lengths, a hanging mass, a meter stick, a stopwatch, appropriate survival equipment, and are transported to the surface of Plunct X. There, they are asked to determine the acceleration due to gravity on the surface of Planet X using just this equipment. () Describe an experimental procedure that the student could use to collect the necessary data as accurately as possible. In order to determine the acceleration due to gravity, the students then create a plot of T vs. the square root of L, as shown below 3.5 1.5 04 12 Square Raat of Length m (d) Using the graph, calculate the acceleration due to gravity on Planet X. (e) Following further analysis and experiments, a comparison of the students' experimental value for the accel- eration due to gravity on Planet X is greater than the actual acceleration due to gravity on Planet X. Offer a reasonable explanation for this difference.

Answer 1

c)

we hang the mass to a string, tilt the string by some angle and release. using the stopwatch , we note the time for one oscillation. then we use another length and tilt the string by some angle and release.using the stopwatch , we again note the time for one oscillation . This way we make a list of lengths used and time period we get for each length. we plot a graph between Time period and squareroot of the length using this data and from the graph we can determine the acceleration due to gravity.
