Can you have centripetal force without 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. The normal force now has a horizontal component, and this component can act as the centripetal force on the car!

What is the centripetal force on a banked curve?

The net force on an object moving in a circle may also be called the centripetal force. This gives the angle necessary for a banked curve that will allow a car to travel in a curve of radius r with constant speed v and require no friction force.

What happens when centripetal force is less than friction?

A higher coefficient would also allow the car to negotiate the curve at a higher speed, but if the coefficient of friction is less, the safe speed would be less than 25 m/s. The centripetal force causing the car to turn in a circular path is due to friction between the tires and the road.

What force is responsible for holding a car in a frictionless banked curve?

friction – the grip between tires and road keeps the car from sliding in the direction of centripetal force.

What is difference between centripetal and centrifugal force?

Centripetal force is defined as, “the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation,” while centrifugal force is defined as “the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of …

Is tension a centripetal force?

A centripetal force is a net force that acts on an object to keep it moving along a circular path. The tension force in the string of a swinging tethered ball and the gravitational force keeping a satellite in orbit are both examples of centripetal forces.

Can friction be greater than centripetal force?

So to stop the generation of force generated by the car, the frictional force must be greater than centripetal force.

What is the centripetal force equal to?

The magnitude F of the centripetal force is equal to the mass m of the body times its velocity squared v 2 divided by the radius r of its path: F=mv2/r. According to Newton’s third law of motion, for every action there is an equal and opposite reaction.

What is the centripetal force of a banked turn?

Suppose we consider a particular car going around a particular banked turn. The centripetal force needed to turn the car (mv2/r) depends on the speed of the car (since the mass of the car and the radius of the turn are fixed) – more speed requires more centripetal force, less speed requires less centripetal force.

How is the centripetal force of a level curve supplied?

=> For a level curve, the centripetal force will be supplied by the friction force between the tires and roadway. => A banked curvecan supply the centripetal force by the normal force and the weight without relying on friction.

Which is the only force acting on a banked curve?

For a banked curve with no friction, the only forces acting on a car are the normal force and the weight. We have just looked at this situation. The centripetal force must be supplied by the horizontal component of the normal force. We have just analyzed this situation in arriving at

Is there a problem with banked curve with friction?

That equation only applies if there is no frictional force acting. The problem does not say there is no friction in the first place. It then asks you to find the friction, implying that it is present. The problem is either flawed or it has not been correctly stated by the OP.
