Newton’s 2 nd Law of Motion Lab 4 Hannah Mayse In this lab, we investigate the rules regarding Newton's Second Law of Motion. Newton’s Second Law establishes a relationship between an object's mass, the force applied to it, and its resulting acceleration. By conducting experiments and analyzing the data collected, we can understand how forces influence the motion of objects with varying masses. We can learn that changes in force and mass effect the acceleration of objects, and we can confirm the fundamental rules given by Newton's Second Law. Part A – Guide Questions 1. What happens to the change in the value of the speed as you increased the amount of force applied on your chosen item? a. As you increase the amount of force applied to an object, according to Newton’s Second Law of Motion, the acceleration of the object increases proportionally. This means that the change in velocity also increases as the force increases. 2. What does this observation tell you about the relationship between the external force applied and a given mass’s acceleration (the rate of change in velocity)? a. Increasing the force applied results in a proportionate increase in the object’s acceleration and the rate at which its velocity changes. Part B Part B – Guide Questions 1. What did you notice with the acceleration values obtained by the different items? What do you think caused the variations in these values? a. The lighter objects have higher accelerations, and the heavier objects have lower accelerations. 2. What variables can you manipulate in the simulation to make all the items get the same proximate values for their acceleration? Explain how this idea will work. a. By adjusting the force applied, you can get the same proximate values for their acceleration. You can increase the force applied to the heavier objects and decrease the force applied to the lighter objects to compensate for the differences in the object’s mass. Concept Check At constant mass, the acceleration of an object varies directly with the net external force applied. That is to say that an object’s acceleration increases as the force applied is increased , but its acceleration decreases if the force applied decreased . At constant force, acceleration varies inversely with mass. When subjected to the same amount of net external force, a heavier object will experience less acceleration than a lighter one. Newton’s Second Law of Motion states that: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The direction of the acceleration is in the direction of the net force. In conclusion, this lab has shown the relationship between force, mass, and acceleration as described by Newton's Second Law of Motion. Through experimentation and data, we have observed that

acceleration is directly proportional to the net force applied to an object and inversely proportional to its mass. Heavier objects require more force to achieve the same acceleration as lighter objects, and we learned about the significance of mass in determining an object's response to applied forces. This lab proves the rules of classical mechanics and contribute to our broader understanding of the physical world.
