Yes it can: if the line of action of the friction force doesn't go through the center of mass, then that force represents a torque.kolua said:can kinetic friction cause a torque? (can it result in rotation)
Or is it that only static friction can cause a torque?
Yes it can: if the object is sliding and rolling you can have what you describe. So in exercises the term "rolling without sliding" may appear to exclude that.Can static friction do work on a rolling object?
I think it can? because the rotational kinetic energy is increasing? is this right?
HELP!
Yes, friction can cause torque on rolling objects. When a rolling object, such as a wheel, comes into contact with a surface, friction acts in the opposite direction to the motion of the wheel. This frictional force creates a torque, which causes the wheel to rotate.
Friction can both increase and decrease the work done on a rolling object. In some cases, friction can cause the object to slow down and require more work to maintain its motion. However, in other cases, friction can be used to do work, such as in the case of brakes on a car.
No, there are other factors that can affect torque and work on rolling objects. These include the shape and size of the object, the type of surface it is rolling on, and the speed at which it is rolling. Additionally, the weight and distribution of weight on the object can also impact torque and work.
Yes, friction can be beneficial in some cases. For example, friction can provide the necessary force to start a rolling object moving, which can then be used to do work. Friction can also help to control the speed of a rolling object, which can be useful in various applications such as vehicles and machinery.
Friction can be minimized by using smoother surfaces, lubricants, or reducing the weight of the rolling object. The type of material used for the object and the surface it is rolling on can also affect the amount of friction. Additionally, keeping the object well-maintained and free of debris can also help to reduce friction and improve its performance.
