can friction cause torque?

Both involve forces, but they are completely separate manifestations of mechanics.killerdoxie said:can friction cause torque?
Yes, friction can cause torque. Torque is a force that causes an object to rotate or spin around an axis. When an object is in contact with a surface, friction can act on the object in a direction perpendicular to the surface. This frictional force can create a torque on the object, causing it to rotate.
Friction creates torque by exerting a force on an object in a direction perpendicular to the surface. This force creates a lever arm, which is the distance between the point where the force is applied and the axis of rotation. The longer the lever arm, the greater the torque.
Yes, torque can be increased or decreased by friction. The magnitude of the torque depends on the magnitude of the frictional force and the length of the lever arm. If the frictional force increases, the torque will also increase. Similarly, if the lever arm is longer, the torque will be greater.
The coefficient of friction is a measure of the level of friction between two surfaces. It can affect torque by determining the magnitude of the frictional force. A higher coefficient of friction means a stronger frictional force, which can result in a greater torque. However, the coefficient of friction also depends on the materials and surfaces in contact, as well as the presence of any lubricants.
Yes, friction can cause both positive and negative torque. Positive torque is when the object rotates in the same direction as the applied force, while negative torque is when the object rotates in the opposite direction. Depending on the direction of the frictional force and the position of the lever arm, friction can create both positive and negative torque on an object.
