balanced forces

1 answer

The correct answer is B. an unbalanced force.

An unbalanced force acting on an object can cause it to change direction. Options A and D might affect the speed of the object but wouldn't necessarily change its direction without being unbalanced. Option C, "no force," would not cause any change in the object's state of motion.
