CALCULATIONS: The vertical velocity for my (Anja's) kick was 11.9 m/s, the horizontal velocity was 11.29 m/s, and the total velocity was 16.4 m/s or 36 mi/hr. The vertical velocity for Zoe's kick was 10.78 m/s, the horizontal velocity was 6.24 m/s, and the total velocity was 12.46 m/s or 27 mi/hr. As you might have seen in the video, my kick was greater and went further the Zoe's because I had more momentum and I used the three step approach (left, right, left). The steps for the calculations are shown in the pictures and the videos above.
REFLECTION: I thought this project went very well. It was fun being able to learn more about making a video and how to kick a soccer ball. I thought we were all able to really take part in this video and I thought it was lot of fun working with new people. I thought we did a good job explaining every step and I feel like we included everything about kicking a soccer ball. I thought it was cool how we interviewed a San Marin player and a goalie. There were a few things I thought we could have could have done better. I think we should have changed the video to make it shorter by removing even more of the calculations as Mr. Williams had suggested and I am just now thinking that it would have been cool if we were to compare our kick to a professional players kick. We did not have any major problems which was nice. I thought we were really able to manage our time. I think this video could be useful for some beginner soccer players.
PROJECT HISTORY: Throughout the past three and a half weeks we have been working on our Physics of Sports Videos. After coming up with ideas for what to talk about, we finally decided that it would be fun to do the physics of kicking a soccer ball! Throughout the process I was able to learn how to make a video, and was able to learn more about the correct way to drop kick a soccer ball. We were able to compare a good kick and a bad kick. We also interviewed a San Marin Varsity soccer player and an experienced soccer goalie.
CONCPTS: momentum- the quantity of motion of a moving body measured as a product of it's mass and velocity. The more momentum you have, the farther the ball can go.
velocity- the time rate of change of position of a body in a specific direction (horizontal velocity is v=d/t; vertical velocity is a=v/t; total velocity is a^2+b^2=c^2). Velocity was used to find the speed the ball went for Zoe and I.
