Does Size Affect How Far A Ball Travels?-Sophia Eloshway
Materials
~2 large tape measurers
~5 small cones
~1 large cone
~ Size 5 soccer ball
~Size 4 soccer ball
~Size 3 soccer ball
~Size 2 (futsal ball)
Variables
The independent variable for my project is the ball size. My dependent variable is the distance the ball traveled each time it was kicked, due to the change of ball size. Finally, the constant is the strength of the kicker, the grass, the wind and temperature, and the same type of kick for each ball.
Hypothesis
My hypothesis is-
Size '3' is going to travel the farthest.
This is because this specific ball size is right in the middle of the other ball sizes. It consists of the right amount of density. Size '4' and size '5' both less dense, and require more power when kicked. Size '2' is very dense, and hard to strike.
Introduction
My topic's purpose was to see if size really does affect the distance a ball travels, or if it depends on the kicker. I tested 4 different sized soccer balls: size '5', size '4', size '3' , and size '2' (futsal ball). My hypothesis was: Size '3' is going to travel the farthest. This was correct.
Abstract
My procedure consists of balls being kicked as far as possible, and to measure we used 5 cones evenly spread apart. If a ball was kicked away from the target area, we did a retake. The sizes had consistent results throughout the experiment. However, size '3' was the easiest to kick, and it traveled the farthest over all.
Abstract (pt. 2)
We measured where the ball came to a complete stop, instead of where it landed. I concluded that size does affect how far it travels. However, I also concluded that it also depends on the person kicking it.
Results
My results showed that size '3' traveled the farthest. This is probably because it is not too dense and it is not to heavy. I also noticed that it traveled in the air the longest. It came almost to a complete stop once it dropped. I also got the best power on this ball.
Conclusions
Yes, size does affect how far a ball travels. My hypothesis: Size '3' is going to travel the farthest, was correct. I learned that depending on the size of the ball, it makes differrent sounds when you kick it. I could improve my expirement in the future by having someone with the same kicking strength assist me.
Procedure
For my procedure I got ball sizes 2-5, and measured the distance they travel each time they are kicked. I spread 5 cones out evenly in a straight line, each of them spread 7 yards apart. Finally, when the ball came to a complete halt, we measured the distance it traveled. We measured ground-balls and air-balls.
Graph
As you can see, size '3' has trveled the farthest.
