Answer 1

Answer:

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.
