Part of their results is displayed graphically nent. S. A group of students performs this experi below. 1.2 0.8 Net force, my8 0.6 0.4 F 0.75 (kg) a-4E-16 (N) 0.2 1.5 0.5 Average Acceleration (m/s) Based upon this graph, what must be the mass of the system they were studying? 4. In part 2 of the experiment, what is the purpose of adding the mass that is taken away from m, and adding it to m? In answering this question, you should address how this allows for you to conduct a controlled experiment.

Explanation / Answer

3] From Newton's 2nd law of motion, the net force on an object is the product of the mass of the object and the acceleration produced in the object.

Fnet = ma

this is of the form, y = mx + c where m is the slope of the y vs x graph and c is the y intercept of the graph.

therefore, if net force is plotted with acceleration, the slope of the graph will give the numeric value of the mass of the object under study. So, to determine the mass here, find the slope of the graph.
