Question

Why is frictional force self adjusting by nature??

Answer 1

Dear Student,

Static friction is the opposing force that comes into play when a body is at rest or tends to move over the surface of another body, but the actual motion has not yet started. Static friction is a self adjusting force because neither it has fixed magnitude nor direction. It adjusts according to the applied force.
Static friction is the only self adjusting force. Limiting and dynamic frictions are not self-adjusting
