If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force<span> (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. </span><span>If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant. the source i found this answer is, https://www.mansfieldct.org/Schools/MMS/staff/hand/lawsunbalancedforce.htm
