Describe how unbalanced & balanced forces are different and how this impacts on motion.

Balanced Forces are different from Unbalanced Forces because Balanced Forces are two forces acting in opposite directions of an object, and equal in size.On the other hand unbalanced forces are forces that cause a change in the motion of an object.

This impacts motion because when balance forces enter,... the object either stops (Stays at rest or moves at the same speed and direction) Unbalanced Forces causes an object to move faster/slower (might change the direction),.. due to one side having more force than the other.
