l Your friend is in a traditional physics classroom and they are investigating circular motion. The class was giiren the foliowing challenge: Three variables inuence the amount of centripetal force required to cause uniform motion. I the mass of the abj - the radius of the Circle I the speed of the obj Perform an experiment that wiii aiiowyou to determine the mathematical retationship between the centripetal force and these three variables. After the lab is nished, students graph their data and then go home to 1iirrite a lab report. Your friend calls you and asks for your help. This is the data he has been given: .Y m0 is. 675] 600 400 200 (2. 25} Jr 0 2 4 6 a 10 Graph 'l Graph 2 Your friend is upset. The graphs don't have any labels! a] Based on your knowledge of Circular motion, how would you label the xaxis and yaxis for Graph 1? ('I mark} b} What variable was being investigated in Graph 2? (1 mark} c] The teacher's note on Graph 1 says 'Experiment errorE\" What is wrong with Graph 1? {1 mark] d] Only 2 graphs are shown here. but there should be THREE graphs in total. Sketch the missing graph and label the x and y axis. [Hint 3 different variables were investigated by students in the physics ctass] {2 marks}
