In this lab we were given the task to find out what the true definition of a projectile is. To figure this out, we went down to the basketball courts and filmed the flight path of a basketball after it had been shot. We were able to find out the acceleration and velocity of the ball in the x and y dimensions.
Vy:
This graph gives us all of the information we need to find the y component of the basketball being thrown. The parabolic shaped graph (top graph) shows us the y position over time, ultimately giving us the value of the slope of the line which is velocity. When looking at the graph you can tell that the slope is not constant, meaning the velocity is also not constant which gives us the idea that the basketball is accelerating.
Vx:
This graph below shows us the x position over the period of time that was taken to record the basketball shot. The slope of this graph is represented by the change in position over the change of time. Unlike the Vy of the basketball, this is constant. THis means that there is no acceleration in the horizontal dimension and that it is constant.
