Read the following excerpt. I arrived with only a few minutes to spare. One of the assistant producers handed me a number and told me to get ready to audition. Surprisingly, there were very few people ahead of me. I sang a few bars to loosen my vocal cords, drank water, and tried to remain positive. I was nervous, but more importantly, I really wanted to get the lead role in this musical.

The center is basically the heart of it

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
