When the car moves in a circular path, due to forces of friction and inertia, the car is always trying to move in straight lines.  This is why inside the car, friction and inertia make up the steering wheel drag force, which is a counterforce to the centripetal force acting on the car.  However, on Earth’s surface, friction is strong enough to make sure that the car’s wheels turn clockwise, and also causes the rate of turn to slow down as the car’s speed increases.  Friction also creates ground under the wheels, allowing the wheels and the car to continue turning in a circle.  Thanks to friction

The force that causes the car you mentioned to follow the circular path you’re describing acts along the length of the circular path.  This force opposes the motion of the car, so that the car doesn’t “drift off” the circular path, which is an example of a centripetal force.  This force is also called centripetal force in physics.  If the car were not on a circular path but instead was free moving, there would be no special force to keep the car on that circular path.  For this reason, the term “centripetal force” is commonly used to describe this force.

Can you explain what centripetal force is in physics?
user
Centripetal force is the force that causes an object moving in a circular path to follow that circular path.  A familiar example of centripetal force is the experience of keeping your car going straight by turning the steering wheel: As the car moves in a straight line, the vehicle spins around the center of the circular path it is following thanks to centripetal force.  Another example of centripetal force is the force that makes a stone fall to the ground around Earth.  As the stone falls towards Earth, the force of gravity pulls the stone towards the center of the planet, creating the circular motion the stone follows as it falls.

Okay. And what force act on the car to keep it on a circular path?
