This … SpletThe top limit of the frictional force that retains an item in a resting posture is known as maximum static friction. When static friction reaches its maximum limit, the item begins to move in the direction of applied force. Ques. What Does µK Mean? (1 mark) Ans. The letter µK stands for coefficient of kinetic friction.

SpletDefinition: Limiting friction is described as the friction created when two static surfaces come into contact with each other. The limiting frictional force is independent of the area of contact and is proportional to the reasonable reaction between the contacting surfaces. Laws of limiting friction: SpletThe static friction between two surfaces in contact is found to be 15 N, then the rolling friction between these two surfaces must be likely to be _____. Q. Assertion :Static frictional force is self adjusting, for the given two surfaces. Reason: Sliding frictional force between two given solid surfaces is independent of surface area of contact. here brighton racecourse
