Physics 131/133 Experiment 1: A Measurement of the Acceleration due to Gravity Abstract: In this experiment, a weight originally suspended by an electromagnet is dropped, and two electrical wires carrying a voltage mark on a strip of wax paper where the weight is during the course of its fall. The charge creates a mark every 1/60 of a second. After determining which dots represent which times and the distance between these dots, we could calculate the acceleration of the weight during the course of its fall. Questions: 1. Newton’s second law of motion states that force is equal to inertial mass times acceleration of the mass, or F=ma. In other words, the force of an object is defined as the mass of that object multiplied by the acceleration of the object. 2. Displacement is the distance that an object moves from its starting point to its ending point. Velocity is how far an object moves in a certain amount of time and in what direction. The units of velocity could be meters per second, miles per hour, or any other unit of distance over a unit of time. Acceleration is an object’s velocity in a certain amount of time. Acceleration occurs when an object speeds up, slows down, or changes
