Answer:
They accelerate.
Explanation:
whether an object is ar rest or in motion, when external, unbalanced forces act on it, the object accelerates, as stated in Newton's second law:
[tex]F=ma[/tex]
where F is the net force acting on the object, m is its mass, and a its acceleration. Therefore, if there are unbalanced forces acting on the object, the object will accelerate. This means that an object at rest will start moving (in the direction of the net force), while an object already in motion will increase (or decrease, depending on the direction of the force) its velocity.
