Our video is about the tennis forehand we show you how to do it and the calculations.
Physics of sports video 1.mov<-- Our Video
We first developed a story board consisting of what should be shown. We thought of the most important steps to hitting a good forehand they where, grip, foot placement, swing path, and momentum transfers. From there we started recording videos on the tennis court and audio in the conference room. We edited it all together and presented out video.
Force of Impact
The force of impact is the force created when two objects meet. The force of impact between the tennis ball and racket is 36.4 kgm/s.
Velocity
Vertical velocity
The vertical velocity is the velocity in the ball in vertical direction. The vertical velocity of the ball is 4.4 /s. that is about 10 mph or average male run speed.
Horizontal velocity
The horizontal velocity is the velocity of the ball in the horizontal direction. the horizontal velocity of the ball is 11.94 m/s. That's about 27 mph or an average electric bike speed.
Total velocity
The total velocity is 12.77 m/s. that is the square root of both velocity. that is about 29 mph or an average speed limit on a road.
Refection
For me this project was a change in step from the last one. We went from build a Rube Goldberg to filming a video. I personally like it. It allowed be to be more creative and reach for farther goals. I learned how to film a video for a presentation like this, instead of portrait you are suppose to film landscape. I was also able to communicate with my team mates and create a good video. For the next project I could work on voicing my ideas more and encourage others to voice theirs.
