This picture shows an example of kinematics because my friends are jumping up with a certain velocity and eventually coming back down with the same velocity they jumped with. Just like in my other blog post, there is a point in time during a jump that your velocity becomes zero due to the gravity factor. If there were no gravity then when we jumped we would never come back down, but since there is, we do come back down but for a split second we are frozen in the air. Also I can tell that my friends are coming down with the same velocity (just in the opposite direction) as they jumped up with because they are starting and stopping at the same level. Just like the volleyball lab we did the other day, after throwing and catching the ball from the same level, we got a pretty accurate reading of its velocity, acceleration and distance.
