Non uniform circular motion and friction

In summary, the forces of a car accelerating around a circle include centripetal force and static friction in towards the circle. However, there may also be other components of friction involved. Friction plays a crucial role in providing the centripetal force and preventing the car from traveling in a straight line. The exact relationship between the two types of friction may vary depending on the specific problem at hand.

What are the Forces of a car that is accelerating around a circle? There is friction between the road and the car.

Centripital force(in towards the circle)
Static Friction(in towards the circle)

However there is also another component of friction that I am missing?
Any ideas?

Thanks

If the car is going around in a circle, its tires are aimed tangent to the circle, not in or out. Isn't there friction between the tires and the road that is accelerating it?

I thought that was the static friction.

Halls didn't claim otherwise. He's telling you that the car is accelerating and suggesting to you what the accelerating force is.

So There is friction perpendicular to the centripital force and friction parallel to centripital force. How are the 2 related?
 
  • #6
Friction provides the centripetal force. Otherwise, the car would travel off in a straight line. Your original question is sufficiently broad that you will have to include the force provided by the engine which acts through torque on the wheels and friction with the road.

Do you have a specific problem in mind?

Is the acceleration uniform and are you given some rate of acceleration?
 
  • #8
No information about acceleration is given. Teacher said that when you draw the right FBD it will become very simple

bump. Any help appreciated. Thanks

Sorry - just got back. I have to think some more about that. I think something is missing.
 

FAQ: Non uniform circular motion and friction

What is non uniform circular motion?

Non uniform circular motion is the motion of an object along a circular path where the speed of the object is not constant. This means that the object is accelerating, changing its velocity, and possibly its direction, as it moves along the circular path.

How is non uniform circular motion different from uniform circular motion?

In uniform circular motion, the speed of the object remains constant, while in non uniform circular motion, the speed changes. Additionally, in uniform circular motion, the acceleration is always directed towards the center of the circle, whereas in non uniform circular motion, the acceleration may not be directed towards the center.

What is the role of friction in non uniform circular motion?

Friction is a force that opposes the motion of an object. In non uniform circular motion, friction can affect the speed, direction, and acceleration of the object. It can also cause the object to slow down or speed up, depending on its direction and magnitude.

How does centripetal force relate to non uniform circular motion?

Centripetal force is the force that keeps an object moving along a circular path. In non uniform circular motion, the centripetal force may change as the speed and direction of the object change. If the centripetal force is not balanced, the object will not be able to maintain its circular motion and will either slow down or deviate from its path.

What are some real-life examples of non uniform circular motion?

Some examples of non uniform circular motion include a car driving around a curved road, a satellite orbiting the Earth, and a rollercoaster moving along its track. In each of these examples, the speed and direction of the object change as it moves along a circular path, making it non uniform circular motion.
