Newton’s Second Law of Motion

The purpose of this investigation is to validate Newton’s Second Law of Motion. In Part A a lab cart will be accelerated by various net forces while keeping mass constant. In Part B the lab cart will be accelerated by a constant net force while its mass is varied. The goal is to determine the relation between acceleration and force and the relation between acceleration and mass. The force on the lab cart is controlled and provided by gravity acting on a weight at the end of a string that passes over a pulley at the end of a lab table. Force, mass, and acceleration all must be measured in order to complete this lab. Force data is collected by calculating the weight of the calibrated masses added to the end of the string. Mass data is collected with a triple beam balance. Acceleration data is collected by a CBR sonic ranging device working in connection with a LabQuest 2 interface. The CBR is connected to DIG1 input that is found under a rubber flap on the LabQuest. The LabQuest interface stores, graphs, and analyzes the motion data allowing the user to determine velocity, acceleration, etc
