What are our Physics of Sports videos? The physics of sports videos our class made are meant to show the physics of a certain sport that would be helpful to anyone who wanted to the play the sport. My group decided on doing a video on ping pong, or table tennis. Making the movie was a fun process and was almost never difficult of frustrating. The video included velocity of the ball, force needed for a good hit, and other helpful physics. It took about two weeks to completely finish.
Reflection I think our group did a good job working together. One thing we did well as a group was splitting the work, because we all did a fair amount of work on filming. Something I could have worked on was staying focused. We were independent during the filming, so it was hard not to get distracted with others doing their filming or other things like that. To fix this, we went outside where people couldn't bother us. Another thing I could work on was actually editing. We did pretty well for our intro, but the rest of the video was bland and boring. To fix this, we added more background music and shortened our voiceovers.
Concepts Force of Impact: The force of a projectile when hit by an object. This can be calculated by using momentum equals impulse, or mv=Ft. This is shown when our ping pong paddle hits the ball. Momentum: Momentum is the tendency of a moving object to keep moving and how hard it is to stop. This is calculated by mass times velocity. This is shown when the ping pong ball moves, and has a certain momentum. Impulse: Impulse is how long and how forcefully something is pushed. This is calculated by force times time. This is shown when the ping pong ball is pushed by the paddle and has a certain impulse. Vertical Velocity: Vertical velocity is how fast an object is going straight up or straight down. This is calculated by acceleration due to gravity times time. This is shown when the ping pong ball is hit to the other side and has a small amount of vertical velocity. Horizontal Velocity: Horizontal velocity is how fast an object is going horizontally. This is calculated by dividing horizontal distance by time. Total Velocity: Total velocity is the total amount a velocity an object goes horizontally and vertically. This is calculated by using a right triangle, or Pythagorean theorem, and finding the hypotenuse of the triangle when the other two sides are the vertical and horizontal velocity. This is shown when we calculated it on a whiteboard and put it in a scene of our movie.
