Why is friction called a self – adjusting force?

Answers

Answered by mrdevansh70

Answer:

Static friction is recognised as a self-adjusting force because it wants the objects to remain at rest not move. Hence, if an external force is applied, the static friction force will be equal to the magnitude of the external force, until it surpasses the threshold of motion.

Explanation:

FRICTION IS CALLED A SELF ADJUSTING FORCE BECAUSE THE FRICTION CHANGES DEPENDING UPON THE CHANGE OF VELOCITY OF THE BODY. IT ALSO DEPENDS ON THE MASS OF A BODY. HIGHER THE VELOCITY MORE FRICTION IS REQUIRED TO BRING THE OBJECT TO REST. ALSO A ROUGH SURFACE IS ABLE TO APPLY MORE FORCE OF FRICTION ON THE OBJECT MOVING UPON IT. DUE TO ITS ADJUSTING WITH THE CHANGE OF VELOCITY OR MASS OR SURFACE ON WHICH IT MOVES SO FRICTION IS A SELF ADJUSTING FORCE.
