You are on a co-op job with a construction firm that has been contracted to build a large waterfront pier on Lake Lanier. You are on-site one afternoon while they are driving the steel footings upon which the pier will be constructed. You watch as a large pile-driving machine lifts a heavy weight to a height of 3 meters above a vertical steel I-beam that is partially embedded in the lakebed. The weight is released, falling along guide-rails to strike squarely atop the I-beam. You notice that the beam is forced down about 14 cm with each drop of the weight. At that moment your co-op supervisor walks up and, as a test, asks you to estimate the average force on the beam during such an impact. She tells you that the pile driver uses a 750 lb weight as its hammerhead. Your first guess is 750 pounds" which she replies, "Try again." What is your second response?

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.
