Today in class, we began with a daily question. The daily question was Why does the vertical component of velocity for a projectile change with time, whereas the horizontal component doesn't? A few minutes were given to us to figure out that the reason is that the vertical component only has one force acting on it, which is gravity. That force has a velocity of 9.8 m/s^2. The next thing we did was a projectile trajectory activity. This activity was trying to figure out what forces acted on horizontal and vertical components. We also did a worksheet, where we had to determine the direction the forces were acting on a ball throw from a pitcher off a mound as it reached its end point. We did a FBD to find the directions. After this part of the worksheet, we had to do calculations finding the delta x of horizontal and vertical motions. The time, acceleration, and initial velocity were given and all we had to do was find the equation to use in order to find the change in x (m). The possible equations were on our equation sheets, under kinematics. The velocity equation and delta x equations were both options. I personally used the delta x equation. After finding the calculations, we plotted them on a graph. After plotting the points, it gave us a half parabola.
