Analysis and Conclusions : This experiment consisted of four different tests that allowed for the calculation of acceleration caused by gravity or to show that the acceleration caused by gravity will remain constant. The tests were two balls of different masses timed during free-fall over a measured distance and a car rolling down two different slopes measuring its change in velocity. While dropping the two different balls at measured heights, I calculated the ball of a smaller mass to have an acceleration ranging between 9.24 to 9.83. The difference in times recorded shows the amount of human error in correctly

Unformatted text preview: releasing the ball each time which can account for the difference of acceleration I had from the know 9.8 meters per second squared in gravity. The same can be said with the greater massed ball with its acceleration ranging from 9.57 to 9.8 m/s 2 . The other tests showing that gravity remains constant on a given slope also had some variances in acceleration usually occurring at the smallest distances. This was caused by the carts wheels having trouble overcoming inertia. When the cart was timed at greater distances the acceleration was much more consistent....
