Final answer:
The net force on a car going around a curve at a constant speed is directed towards the center of the curve, known as the centripetal force.
Step-by-step explanation:
The net force on a car going around a curve at a constant speed is directed towards the center of the curve. This net force is called the centripetal force, which is responsible for keeping the car moving in a curved path. The direction of the net force is always perpendicular to the velocity of the car at any given point along the curve.
