Velocity of 0

My picture is one of my dad jumping the highest he could go in a bounce house. This shows an example of kinematics because he’s jumping up with a specific velocity, and when he comes down, he’s returning with the same velocity that he started with. There’s a point in his jump where he’s at a velocity of zero just like when we throw an object in the air. If you take a rock for example, if you throw it up at a velocity of 10 m/s, it’s going to return to the same spot you threw it from at the same velocity (just like bullets do when people shoot them in the air at celebrations). But there’s also a point when the rock reaches a certain point and for that split second, the velocity of it is zero. Just like the rock, my dad isn’t going to be at a velocity of zero for a long time, but during that time frame he is. Also being still for a little while allows for a picture to be taken without becoming blurry.
