#### Transcript of Angles and Soccer

Conclusion
I investigated at what angle is the most accurate when shooting on net. My hypothesis was supported because at ninety degrees there was a 100% scoring shot. I found at ninety degrees all three shots were made, no other angles proved to be that accurate. senty five waas the next closest with a 66.6%. I learned that when you are shooting a soccer ball you have a greater chance of scoring t a ninety degree angle then any other angle.
Question and Hypothesis
Materials
To perform this experiment you need cleats, a ball, a pencil, paper, a goal, some type of barricade, protractor, tape measure.
Research Paper

Angles are crucial in soccer, they let the shooter have an easier or harder time scoring. That is why many pros use bending the ball and power to their advantage. This experiment proves that angles are key when playing soccer.

Curving the ball takes time and practice but knowing how and why it happens is different."Ant ball that is spinning on ab axis that is perpendicular to the ground will move sideways do to the Magnus Effect" (Davy, 2003). " The spinning creates a whirlpool effect which causes the air pressures to be different on one side of the ball then the other" (Lerner, 2007). Its comparable to how an airplane gets lift with the air pressure on different sides.

Angles will help the worst and the best players score.Shooting from a ninety degree angle is better then shooting from a fifteen degree angle because more of the goal is open and not blocked by the goalie. fifteen degrees is a lot closer to zero degrees then ninety and a zero degree shot is the most difficult next to a shot behind the goal. If you draw lines from the goal posts out to the eighteen yard line then that's the most dangerous place to score from (Parrish, 2011). Knowing that angles help can improve any players performance on the pitch.

For a powerful shot its best to use kinetic energy. " To find the kinetic energy you use the formula Ke= 1/2mv2, kinetic energy is where the first object is in motion and affects another in any way (World of Physics, 2007). Another key part to having a powerful shot is keeping your knee over the ball.

Curve, angles, and power each use a different kind of math. Angles use geometry, power uses kinetic energy, and curve uses physics. Each kind helps the player score and dominate. The research helps to show how the physics and math go into shooting a ball effectively.
Analysis
I found that my hypothesis was supported because at ninety degrees I made all the shots which was the greatest percent out of all the angles.
Angles and Soccer
Procedure
Measure the length of the goal
Divide that by three
Multiply that by two and cover up that much of the goal
Find the midpoint of the open area and mark it
Measure out 15, 30, 45, 60, 75, and 90 degrees with the protractor and mark each angles after measuring out 18 yards from the goal
Shoot the soccer ball from each spot three times and record the data after each
Variables
Independent Variable: Angle of shot
Dependent Variable: Accuracy of Shot
Constants: Ball, kicker, cleats, angles, barricades.
Control: 90 degrees

Question: What angle facing a soccer goal that only one third is open has the highest chance of scoring with curve on the ball
Hypothesis: I think that ninety degrees or straight at the goal will have the highest percent because you do not need curve.
Accuracy of shot (%)
