## What kind if any of curve can a car negotiate if there is no friction between the tires and the road?

ideally banked curve
In an “ideally banked curve,” the angle θ is such that you can negotiate the curve at a certain speed without the aid of friction between the tires and the road.

At what speed is there no frictional force between the car and the banked curve?

If the car has a speed of about 11 m/s, it can negotiate the curve without any friction.

### What direction is friction on a banked curve?

The frictional force →Fs−fricTCis has to be at right angles to the normal force. The net force Fnet must be horizontal and towards the centre of the curve.

Can the car make it around the curve without skidding?

If the road is banked at the proper angle θ, a car can round a curve without the assistance of friction between the tires and the road and without skidding.

#### Is it possible for a vehicle to travel around a curve without accelerating?

Explanation: An acceleration is necessary for an object to change direction. The car experiences a centripetal force as it turns the corner as a result of friction. The magnitude of the velocity does not change, but the direction does.

Why is friction equal to centripetal force?

1: The frictional force supplies the centripetal force and is numerically equal to it. Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the Fc, the smaller the radius of curvature r and the sharper the curve.

## Which direction is friction on a banked curve?

At what maximum speed can the car navigate the curve?

25 m/s
The maximum speed at which the car can negotiate this curve is 25 m/s. Car B uses tires for which the coefficient of static friction is 0.85 on the same curve.

### Can a car make a banked turn with no friction?

Well, yes, it could happen if the curve is banked, and the car had precisely the right speed. Here’s how: All forces on the car are vertical, so no horizontal force can be generated. The normal force on the car due to the road is no longer vertical, so a component of the normal force acts in the horizontal direction.

What happens when friction is present in a banked turn?

In this case, the horizontal component of the normal force will be greater than the required centripetal force and the car will “want to” slide down the incline toward the center of the turn. If there is a friction force present between the car’s tires and the road it will oppose this relative motion and pull the car up the incline.

#### What happens to a car when there is no friction?

If there is no friction, there is no force that can supply the centripetal force required to make the car move in a circular path – there is no way that the car can turn. On the other hand, if the car is on a banked turn, the normal force (which is always perpendicular to the road’s surface) is no longer vertical.

What is the force of a frictionless banked curve?

The frictionless banked curve exerts a normal force F n perpendicular to its surface. The downward force of the gravity F g is present. The two forces add as vectors and the resultant or net force F n e t points toward the center of the circle.
