Final answer:
Unbalanced forces cause a change in motion, while balanced forces do not.
Step-by-step explanation:
The type of force that does not cause a change in motion is called an unbalanced force. Unbalanced forces cause a change in an object's motion by either speeding it up, slowing it down, or changing its direction. On the other hand, a balanced force does not cause a change in motion as it cancels out the effects of other forces. For example, if you push a book on a table with a force of 5 N to the right, but there is an equal opposing force of 5 N to the left, the book will not move because the forces are balanced.
