This force causes objects to slow down , speed up, or change direction. __ Strong Force Balanced Force Balanced Unbalanced Force Equal Force

## Step 1<br />The problem is asking us to identify the type of force that can cause an object to slow down, speed up, or change direction. <br /><br />## Step 2<br />Let's analyze each option:<br /><br />- Strong Force: This is a fundamental force that acts between quarks, the basic building blocks of matter. It is not the force that causes objects to slow down, speed up, or change direction.<br /><br />- Balanced Force: Balanced forces are equal in size but opposite in direction. They cancel each other out, resulting in no change in the object's motion. Therefore, they do not cause objects to slow down, speed up, or change direction.<br /><br />- Balanced: This term is not a type of force. It refers to a state where forces are equal and opposite, resulting in no change in the object's motion.<br /><br />- Unbalanced Force: Unbalanced forces do not cancel each other out and result in a net force. This net force can cause an object to slow down, speed up, or change direction.<br /><br />- Equal Force: Equal forces are forces that have the same magnitude but may not necessarily be in the same direction. They can be balanced or unbalanced, depending on their direction.<br /><br />## Step 3<br />Based on the analysis, the correct answer is "Unbalanced Force" because it is the force that can cause an object to slow down, speed up, or change direction.
