Description
In High School Physics A, we learn about mass and weight, their differences and their measurements. In class we perform a Lab experiment: We have a spring, a ruler and weights of known mass. We place the zero of the ruler on the end of the spring hanging from a fixed point. Then we place known weights in succession and note the values of mass and elongation in a table. At the end, we make a diagram with these values. Here the force is the weight, so the elongation is proportional to the weight and since mass is proportional to the weight (B=mg) then mass is also proportional to the elongation of the spring. We can perform the same exactly experiment virtually, online, using a Simulation. We carry out the virtual experiment so that students can answer the question: What is the relationship between mass and elongation of the spring?

Procedure on how to put in practice
This Simulation, when conditions do not allow a hands-on activity, can also help students reproduce at home the experiment we can do in the laboratory. Place the known weights in sequence, noting the values of mass and spring elongation in a table and make a “Mass - Spring elongation” diagram. Observe that mass is proportional to the elongation of the spring.
