# Newton's Second Law of Motion

The objective of the experiment, entitled Newton’s Second Law of Motion, is to verify the direct proportionality of acceleration and net force if the mass of the body is constant and to verify the inverse proportionality of acceleration and mass if the net force is constant. It is now clearly explained and proven that Newton’s second law of motion is true. By experiments, the law is proved. All data produced results parallel to what Newton states. We can say that the acceleration is directly proportional to the net force if the mass of the body is constant. The acceleration increases as the net force increases. The acceleration is inversely proportional to the mass if the net force is constant. The acceleration decreases as the mass of an object increases.

We also found out that the change in net force greatly affects the acceleration than of the change in mass of an object. This is proved by the third part of the experiment. When both the mass of the object and the net force increases, the change in net force will produce greater effect on the acceleration. We can also say that the acceleration will follow the direction of the net force. mass| net force| acceleration|

0.02 kg| 0.916 N| 0.36 ms2|

0.04 kg| 0.592 N| 0.60 ms2|

0.06 kg| 0.588 N| 0.76 ms2|

0.08 kg| 0.784 N| 0.87 ms2|

0.1 0kg| 0.980 N| 0.96 ms2|

Newton’s second law of motion, the most important and useful of the three, establishes a relationship between the unbalanced force applied to an object and the resultant acceleration of the object. This relationship states that an unbalanced force acting on an object produces an acceleration that is in direction of the force, and inversely proportional to the mass of the object. In other words, force equals mass times acceleration, or F = ma. Thus, a given force will accelerate an object of small mass more rapidly than it will on object of larger mass. Similarly doubling the applied force produces...
