Multiple Choice Bubble the correct answer. Use the image below to answer question 1. 20 N 10 N 1. The skateboard above moves at a constant velocity before the two forces shown suddenly act on it. What happens to the skateboard? SC.6.P.13.3 A The forces are balanced, so the skateboard accelerates. B. The forces are unbalanced, so the В skateboard accelerates. The forces are balanced, so the skateboard continues moving at the same velocity. D The forces are unbalanced, so the skateboard continues moving at the same velocity

B. The forces are unbalanced, so the skateboard accelerates.

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.
