When a car rounds a corner, it is subjected to a force known as centrifugal force, which is the force that acts on a body moving in a circular path and is directed away from the center of the circle. Centrifugal force is often described as a “fictitious” force, because it is not a real force like gravity or electromagnetism, but rather a result of the body’s inertia as it moves in a circular path.

As a car rounds a corner, the centripetal force, which is the force that acts on a body moving in a circular path and is directed toward the center of the circle, causes the car to accelerate. This is because the centripetal force is counteracted by the friction between the tires and the road, which propels the car forward.

There are several factors that can influence the acceleration of a car as it rounds a corner, including the speed of the car, the radius of the corner, the coefficient of friction between the tires and the road, and the mass of the car.

The speed of the car is an important factor in determining the acceleration of the car as it rounds a corner. The faster the car is traveling, the greater the centrifugal force and the greater the acceleration. However, if the car is traveling too fast, it may lose traction and skid, resulting in a loss of control.

The radius of the corner is another important factor. A smaller radius means a sharper turn, which results in a greater centripetal force and a greater acceleration. Conversely, a larger radius means a gentler turn, which results in a smaller centripetal force and a smaller acceleration.

The coefficient of friction between the tires and the road is also important. A higher coefficient of friction means that the tires have a greater ability to grip the road, which results in a greater acceleration. A lower coefficient of friction means that the tires have a lesser ability to grip the road, which results in a smaller acceleration.

The mass of the car is also a factor in determining the acceleration as it rounds a corner. A heavier car will have a greater inertia and a greater resistance to change in velocity, resulting in a smaller acceleration. A lighter car will have a lesser inertia and a lesser resistance to change in velocity, resulting in a greater acceleration.

In summary, a car accelerates as it rounds a corner due to the interaction between the centripetal force and the friction between the tires and the road. The acceleration of the car is influenced by several factors, including the speed of the car, the radius of the corner, the coefficient of friction between the tires and the road, and the mass of the car.
