What could the student do to improve the accuracy of his investigation? Tick one box. Use a longer to measure the length Use a pointer from the spring to measure the length Use a new spring between each reading Use a stronger spring in the investigation (1) (d) The weight on the spring is the force applied to the spring. The student puts a mass of 25 g on the spring. Gravitational field strength = 9.8 N / kg Calculate the weight on the spring. Use the equation: weight = mass × gravitational field strength ___________________________________________________________________ ___________________________________________________________________ ___________________________________________________________________ Weight on spring = _________________ N (3) (e) The student plotted a of force applied and extension of the spring. Figure 2 shows his graph. Figure 2 What is the relationship between force applied and extension? Tick one box. Extension is directly proportional to force Extension increases by smaller values as force increases Extension is inversely proportional to force (1)
