It depends. If the net force is unbalanced the velocity will change.

It's true as long as you pay close attention to your definitions. In this statement by "velocity" you must mean the velocity vector of the object, not just how fast it's going.
A net force will cause the object to have an acceleration for the entire time interval the force exists. During that interval the velocity vector will change, but it is possible that the change could be a change in direction or speed (increase or decrease) or both.

If an unbalanced force act on an object either the velocity or vector has to change, probably both.

A)=B)-T speed=speed,no? if acc. alterations,speed will substitute... C)-F you like a tension to overcome friction,no friction,no tension needed D)-T if at relax,his speed is 0,no speed,no acc.,no tension... E)-F no,they could have diff.mass.. F)-T the truck has larger mass...f=mxa,2d=fxv
