* Acceleration: Unbalanced forces cause an object to accelerate. This means its speed or direction (or both) will change.
* Speeding Up: If the unbalanced force is in the direction of the object's motion, it will speed up.
* Slowing Down: If the unbalanced force is in the opposite direction of the object's motion, it will slow down.
* Changing Direction: If the unbalanced force is perpendicular to the object's motion, it will change direction.
Think of it this way: Unbalanced forces are like pushes or pulls that have a stronger effect in one direction than another. This imbalance causes the object to move in the direction of the stronger force.
