MASS AND ACCELERATION OF A FALLING BALL OCTOBER 27 TH , 2010 Performed by: Shraddha Pai, Michael Gerszewski and John Mainz TA Name: Barry Nicholas Costanzi STATEMENT OF THE PROBLEM: The problem was to determine the dependence of acceleration of a ball on its mass. We took three different balls, with different masses but approximately the same diameter and dropped them from a height one by one. Videos of the motion of the balls were taken using a camera and later, the motion of the balls were analysed using the LabVIEW TM PREDICTION: Our group predicted that the motion of the balls will be independent of the mass of the balls. We thought so because when a body is thrown down or released from a height, it experiences a free fall situation. In free fall, the objects experience acceleration due to gravity which is the same for all objects close to the earth irrespective of their masses. We know that the force of attraction due to the earth’s gravity causes an acceleration given as follows: = mg GMmR2 Therefore, = g GMR2 Where, M is the mass of the attracting object ( Earth in this case)

r is the distance between the two objects. G is the gravitational constant of the universe. Thus, we felt that disregarding air resistance, all small masses dropped
