Newton’s Second Law Lab By: Cc Larrazabal, Kathleen Boyce, Garrett Burdin 9/19/18 First Experiment What effect does changing the net force on a system have on the acceleration of the system? IV: net force DV: acceleration CONSTANT: total mass Lab Setup (pictured at the right) Method: Measure the total weight of the cart, change the net force and record the acceleration of each different variable. Procedure
Data: Chart pictured to the right Graph: pictured under chart ( clearer version at bottom of page) Second Experiment What effect does changing the total mass of a system have on the acceleration of a system? IV: Total mass DV: Acceleration CONSTANT: Net force Lab Setup (same as first experiment) Method: Change total mass of hanger and measure acceleration for each different variable. Procedure

Conclusions: Through these experiments my group and I were able to discover and understand Newton’s Second Law. From the first experiment I was able to find a linear relationship between the net force of the hangar and the acceleration and figure out that it is actually supposed to be directly proportional. The second experiment allowed me to discover that the mass of a system and its acceleration are inversely related. These experiments helped prove the law to me to be able to better understand it.
Uncertainties: The biggest source of uncertainty for my experiment was time due to the fact that we couldn’t let the hangar crash into the ground or the cart hit the end of the ramp we only had a very small amount of space to actually record data which led to a small time gap.
Improvements: In order to fix our uncertainty we would need a longer ramp to allow the cart to run for a longer time which would produce more data.
