Abstract- The results of this experiment were relatively accurate. The three different calculated values of the force of gravity were fairly close to the accepted value of gravity. The calculated values varied from the accepted value of gravity at roughly .3 m/s 2 . The results of this experiment can be used to explain that the rate of gravity is the same on every object despite the object’s mass, the object’s size or the object’s height from which it is dropped. Discussion- The purpose of this lab was to prove that the magnitude of earth’s gravitational force is the same regardless of the falling object it is affecting. To do this, the equation d = ½gt 2 , which represents the relationship between distance (d), the rate of gravity (g), and time (t), was used as a basic foundation for all other equations. A plastic golf ball and two steel balls with different masses were tested multiple times at different heights with the purpose of finding the rate of gravity. In order to prove this, many different tools were used to calculate the time it took for each object to reach the ground. A magnetic drop box and timer switch were used to hold and release the objects from a certain height. A target pad was used to calculate the amount of time it took for the objects to fall from a certain height. A
