Why is static friction called self adjusting friction |
| Answer» Static friction is the opposing force that comes into play when abody is at rest or tends to move over the surface of another body ,but actual motion has no yet started. Static friction is a self adjusting force because neither it has fixed magnitude nor direction . It adjusts according to applied force. | |
