For the last term, We have been doing a science project. My topic was what effect does gravity have on the falling speed of balls. My research that I looked up showed that a heavier ball would fall faster. For my test, I used a video camera to video the results. The balls I used were a tennis ball(50g) a beach soccer (270g) a soccer ball(380g) a basket ball(450g) and a medicine ball(5kg) . In my testing it showed that I was wrong and all balls fell the at the same rate. One site told me why this happened. Gravity has more pull on a heavier object but, it takes more gravity for the ball to accelerate. These two factors cancel each other out. From this science fair, I learned how to set up a science fair and what order to put the writing. I also learned that gravity has the same effect on all balls when they fall. Over all I am happy with my science fair. Next time, I’d like to get done earlier.
