Blog 2: Fetch

      Today I was playing fetch with my dogs, their favorite type of daily exercise and realized once again that physics was involved. When I threw the ball for my dogs, I was performing a projectile motion. Once the ball left my hand, it had a horizontal velocity, the x component, and a vertical velocity, the y component. As the ball left my hand the vertical velocity decreased until it reached the peak and then began increasing velocity until it hit the ground, or on a good day my dog caught it. But as the vertical velocity changed, the horizontal velocity stayed the same through out the whole throw because it was not accelerating in the horizontal direction. Now if I had the actual horizontal and vertical velocity, I could take those numbers and then find out the vector and the angle of my throw. But maybe today we just play and save the experiment for another day.
