Abicycle speeds up as it moves along a flat road. what happens to the bicycle’s gravitational potential energy during this time?

1.it decreases.

2.it increases.

3.it remains the same.

It remains the same because without an uphill or downhill the speed stays the same

It stays the same since there are no changes in elevation. GPE is given by mgh. Since h remains constant on a flat road, so does GPE

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.
