Lab 6 - Dynamics: FNet = ma Introduction: The purpose of this lab is to explore the relationship between acceleration. mass. and unbalanced force (also called net force). and to verify Newton's Second Law. According to Newton's Second Law (FNet = ma). the unbalanced force (also called net force) is proportional to the acceleration of the system. If more force is applied to the system. its acceleration will be greater. In fact. if the force is increased while the mass (m) of system is kept unchanged, the relationship between the net force and acceleration will be proportional. That means that doubling the net force will resulting doubling the resulting acceleration. It also means that if one would plot a graph putting the genome as yaxis and ameletationas x-axis, he or she would see a linear trend that originates at the zero point (the point where x and y axis cross). Not that it is the net force, not the applied force that is proportional to the acceleration. So. doubling only the applied force will not result in twice as much acceleration. In this lab, we will test Newton's Second Law by verifying that the net force versus acceleration graph is in fact linear when mass is kept constant as predicted by Newton's Second Law. 1) In the simulation go to the Acceleration section (the bottom right picture). 2) Check all the boxes so numerical values will be shown. 3) First, make the applied force 100 N and observe what happens to the box. Record the values of the applied force, friction force. and acceleration in the table below, 4) Retry the experiment by increasing the applied force in 50 N increments and fill out the table below. 5) Using the link below. plot net force versus acceleration graph, f ' ' I 6) Take a screenshot ofthe graph and include it in your lab report submission.

What trend do you see in the graph. Was the graph linear? 02) In step 3, the applied force was made equal to 100 N, the box did not move. What would you say to a student who claims that this observation contradicts Newton's ll law since the applied force is there but the box did not accelerate? Q3) Explain how the table in the previous page support the statement that sliding friction force is independent ofthe speed of the siding object. 04) Try this out in the simulation. Once the box starts sliding. change the applied force to zero. You will notice that the box does not stop right away. Is this a glitch in the simulation or is it an expected outcome? Explain
