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....
