Imagine yourself in a car traveling around a sharp curve. The "centripetal" force is inward, yet why do you slide outward and not inward?
What will be an ideal response?
In the absence of an inward force, you want to continue in a straight line which would cause you to move "outward". The frictional force of the seat or the push of the side of the car pushes you "inward" and supplies the centripetal force to keep you on your circular path.
