Q: Matilda and Ravi carried out an experiment with springs. They put different masses on the spring and measured the length of the spring each time. a: Draw a graph to show the results.
b: What is the best conclusion for this experiment:
i: The bigger the mass, the larger the weight.
ii: The larger the weight, the longer the spring.
iii: The longer the spring, the bigger the weight.
c: Ravi uses the same spring and hangs different objects from it. He uses his graph to work out the weight of each object. The table shows his results:
