Explicación
## Step 1The problem is asking us to identify the type of force that always causes a change in an object's motion. The options provided are contact, unbalanced, non-contact, and balanced forces.## Step 2Let's analyze each option:- Contact forces are those that require physical contact between the objects involved. They can be balanced or unbalanced.- Non-contact forces are those that do not require physical contact between the objects involved. They can also be balanced or unbalanced.- Balanced forces are those that are equal in magnitude and opposite in direction, resulting in no change in motion.- Unbalanced forces are those that are not equal in magnitude and/or not opposite in direction, resulting in a change in motion.## Step 3From the above analysis, it is clear that unbalanced forces are the ones that always cause a change in an object's motion.
