The statement that is true about unbalanced forces is: they can change both an object's speed and direction.
The correct statement about unbalanced forces is:
"They can change both an object's speed and direction."
When multiple forces act on an object and the net force is not zero, we say that the forces are unbalanced. This means that there is an overall force acting on the object in a particular direction. Unbalanced forces can cause an object to accelerate or change its motion.
To understand this concept, consider Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (a = F/m).
When unbalanced forces are present, the acceleration experienced by the object is in the direction of the net force. This change in acceleration can result in a change in the object's speed. If the net force acts in the same direction as the object's initial velocity, the object can speed up. Conversely, if the net force acts opposite to the object's initial velocity, it can slow down.
Additionally, unbalanced forces can also change the object's direction. For example, if an object is moving in one direction and a force is applied perpendicular to its initial velocity, it will experience a change in direction.
Therefore, the correct statement is that unbalanced forces can change both an object's speed and direction.
