Acceleration Due to Gravity Objective: The objective of this lab is to determine the e.eration du_ t. god. ity new. the earth $ Surfuve by dropping a bul f.om a ce. twin height nut. s_ _ ir different i_es of object Ial ut the same tine or not. I L.-uucti . in this lub we a e going t. igno ~ the effect of ai ce_istance when we drop un object newt the s race of the earth it will travel down with a constant acceleration , 9.8 m/s- on the way down unu g- y 8 m/s on the way up. This failing object obeys the lanematic equation which is given by: Ay - vit - 1_ _to where by is the displacement of the falling object in time t. For an object initially at rest falling in a gravitational field, the , revious e. uation reduces to y .!_ _to where y is the vertical height and t is the time of fall. In this lab, once we measure the time it takes a free falling object to fall a certain distance we can determine 5. Theory: Gravity is what makes things fall down; but what is gravity? Sir Isaac Newton tried to e plain gravity by seeking out the laws according to which it acts. Objects near the surface of the earth fall toward it with an acceleration, due to the gravitational attraction of the earth. How can the earth make bodies fall towaru it? Has the acceleration due to gravity always stayed the same or does it change? These questions and others about gravity have yet to be answered. In doing this lab, you will become more familiar with the effects of gravity on falling objects by measuring the acceleration due to gravity experimentally and compare it to the accepted value of 9.8 m/secz.
