Caddo's Blogger: Oscillating Mass Lab
Caddo's Blogger: Oscillating Mass Lab: In this lab, we hooked different amounts of mass to a spring. We would measure the springs displacement by subtracting the length of the spr...

Newton's Second Law (F = ma)
Newton's Second Law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
During class we demonstrated Newton's Second Law by rolling a chair in the hallway. We rolled the chair three different ways, with each starting at a gradual acceleration and a fast acceleration: the chair by itself, the chair with our partner, and the chair with a forty-five weight and our partner. At the end of the demonstration, we learned that when the force applied to the chair was increased, the acceleration of the chair was also increased; however, when we added our partner or our partner with the weight, the acceleration decreased because the mass had increased.

2 dimensional motion: horizontal initial velocity
2 dimensional motion: horizontal initial velocity
PROCEDURE:
Video
DATA:
Time- .34 seconds
Initial Velocity= 1.59
Change in X=.6996
total time=.435
Analysis:
Data
CONCLUSIONS:
While we were doing the lab, we had difficulties with the timer. Also, our calculations never came out reasonable. When we were done we went back and tested it and see if the calculations were precise. Unfortunately, they weren’t. The second time around they came out correct.In the future, we can use this calculations for drop offs while flying or parachuting or something fun like that.
