Name: Fernando CamposPHYS.1410L, Laboratory (817)9/28/2016TA’s name: Hridaya ShahExperiment #2Motion in Free-FallObjective: To measure the rate at which the velocity of afree-falling object changes with respect to time, whichwill determine acceleration due to gravity (g).
IntroductionWhen force acts upon an object, that force causes the object to accelerate. If the magnitude of theforce is constant, then the acceleration of the object will also be constant. A free-falling object, isacted upon the force of gravitational attraction between that object and the earth, and is directedtoward the center of the earth. When the distance of the fall is significantly smaller than theearth’s radius the gravitational force is constant, and the acceleration due to gravity (g) will alsobe constant. There is of course a second force acting upon the object (air resistance) which wewill ignore. We ignore this force because a smooth, dense object falling only a short distance, airresistance is very small. Its effect can be ignored in the present experiment.Equations:Slope formula, used to find the slope of the line of best fit:m = (rise/run)=(yf-yi)/(xf-xi)----------------(1)Where “m” represents slope and “yf-yi” stands for the change in (y) and “xf-xi” stands for thechange in (x).The acceleration can be defined as the rate of change of velocity over time:a = (v – v0) /t ----------------------------------(2)Where “a” stands for the acceleration of the object, “v” is the final velocity and “v0” is the initialvelocity.The average velocity (v) of a body is defined as the total displacement (s) travelled by the objectdivided by the time (t) taken to travel that displacement:v = s / t ----------------------------------------(3)The average velocity calculated in the form of a simple line equation (y = mx +b):v = v
