which statement is true about unbalenced forces.a car travels
they can change both an objected speed and direction
they can only change an objects direction
they have no impact on an object in motion
they only change an objects speed
The statement "They can change both an object's speed and direction" is true about unbalanced forces.
The correct statement 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."
To understand why this statement is true, let's start by explaining what unbalanced forces are. Unbalanced forces refer to any forces acting on an object that are not completely offset by equal and opposite forces. When unbalanced forces are present, the object tends to experience a change in its motion.
Now, let's break down the other answer choices:
1. "They can only change an object's direction": This statement is incorrect because unbalanced forces not only change an object's direction but also its speed. If there is a net force acting on an object, it will accelerate either in the direction of the force or opposite to it, depending on the circumstances.
2. "They have no impact on an object in motion": This statement is also incorrect. Unbalanced forces can indeed have an impact on an object in motion. If unbalanced forces act upon an object, they will either speed it up or slow it down, ultimately changing its motion.
3. "They only change an object's speed": This statement is incorrect since unbalanced forces can change both an object's speed and direction.
So, the correct statement is that unbalanced forces can change both an object's speed and direction.
