Does the static friction have an x-component that is the centripetal force and force in the y-direction that is the tangential force - which keeps the child moving tangentially to the circle with 0.5m in radius?TSny said:
Whether you call them x and y like that is up to you, but yes, the static friction must account for the net acceleration, and this will have both a radial (centripetal) and tangential component.Warlic said:
Static friction is a type of force that prevents two stationary surfaces from moving against each other. It occurs when there is no relative motion between the surfaces.
The direction of static friction depends on the direction in which an object is being pushed or pulled. It always acts in the opposite direction to the applied force, preventing the object from moving.
Static friction occurs when there is no relative motion between two surfaces, whereas kinetic friction occurs when there is relative motion between the surfaces. Additionally, the force of static friction is usually greater than that of kinetic friction.
The strength of static friction is influenced by the type of surfaces in contact, the force pushing or pulling the object, and the normal force exerted on the object by the surface it is on. It also depends on the roughness and texture of the surfaces.
Yes, the direction of static friction can change if the direction of the applied force changes. It will always act in the opposite direction to the applied force, preventing the object from moving.
