Final answer:
If an object is moving to the right and there is a net force acting on it to the left, the object will slow down.
Step-by-step explanation:
If an object is moving to the right and there is a net force acting on it to the left, the object will slow down. This is because the force is acting in the opposite direction to the object's motion, causing it to decelerate.
For example, if a car is moving to the right and a strong wind is blowing to the left, the car will slow down.
