Name of School: Tampines Junior College
Subject of spa: Physics
Month of attempt: May
Skill: B only
Number of attempts: 1/3
Topic on: Newtonian Mechanics
Set up:
You are provided with 3 retort stands, one string, some assorted weight, a rule that can sag easily, one metre rule
You are to take 6 different readings. There are in all 6 columns, m,/g (ho-h)/cm (loading), (ho-h)/cm (unloading), average (ho-h)/cm. Determine lg (m/g) and lg [(ho – h)/cm].
Plot the data points and draw the best-fit line.
Shape of Graph: A straight line graph must be obtained.
Other measurements/values we must find: None.
Precautions for marking scheme: Ensure that the metre rule used to measure deflection is vertical, and that the two points of support are not shifted throughout the whole experiment. Measure h at the same point of rod at ho.

A/N: Temasek Junior CollegeÂ’s SPA assessment attempts (2/3) for Skill B was exactly the same as the following experiement except that an extra needle and blutack were given out during in the experiment. This needle should be attached to the 50cm mark of the ruler using the blutack and acts as a pointer and thus, helps the student take the readings more accurately.
