Name: Bryan Meza Lab #4C: Newton’s 3 rd Law Objectives: By examining the graphs that these sensors will produce, we will employ two force sensors in this lab to test Newton's Third Law. The direction of the link between force pairs and the variance of force pairs will be observed. We will be able to comprehend and express Newton's Third Law in straightforward terms by the end of the experiment. Equipment: Station #: 5 Partner: Kennadee Anderson , rating: #5/5  Computer  LabQuest Mini Interface  Logger Pro  Two Vernier Force Sensors  1 or 2 N calibration weight  String  Elastic Preliminary Questions: #1: Because the force the bug exerts on the windshield is equal to the force the windshield exerts on the bug, it would be neither, according to Newton's Third Law. They have the same magnitude but face the opposite way. #2: The rubber band is pulling on my right hand with some power. My left hand pulls on the rubber band, while my right hand pulls in the opposite direction. #3: My right hand increases the force it is applying. #4: My right hand pulls in the opposite direction with the same force as my left hand when I apply pulling pressure to my left hand using a rubber band. Procedure: Using two force sensors that will graph the forces applied to them, we are testing Newton's Third Law in this lab. In order to graph the data on Logger Pro, we first had to set up everything, including the LabQuest Mini and two force sensors. We had to calibrate the sensors in Logger Pro once we had it connected and functioning properly. To test whether Newton's Third Law is true, we began graphing by pulling each sensor with a string and a rubber band. Step #9:

String Rubber Band Prediction Rubber Band

Analysis: #1: The Third Law of Newton states that although the magnitude of the forces will be equal, the directions of the reaction forces will be in opposition to one another. #2: In the case of a rubber band, the tension will decrease as the band lengthens. The reaction forces, however, will remain constant and move in the opposite direction. #3: No, when we pull on each other's force sensors, the sensors do not all point in the same positive direction. The manufacturer specifies the positive direction of each force, which is typically the direction in which the force sensor is most sensitive. My force sensor's positive direction in this situation. is toward my partner, and the force in my partner's favor is moving in my way. As a result, the force sensor on my partner's body will register a positive force when I pull on it, whereas the sensor on his body will measure a negative force. Since two forces are acting in opposition to one another, this affects how the force pair is analyzed. #4: My partner and I may pull together while they held their sensor firmly in place on the table. #5: The expression "forces A and B are equal and opposite" denotes that the forces' intensities are equal and that their directions are opposite. Their sign points in the wrong way. Due to their equal magnitude and opposing direction, the forces actually cancel each other out. According to Newton's third rule, there are always two forces operating on the objects involved in an interaction. The magnitude of the forces acting on the first and second objects are equal. #6: The bug and and windshield is zero since they cancel out according to Newton’s Third Law.
