Question

Friction that exists between two surfaces in contact, when there is no relative motion between them is called as?

Answer 1

Hint: Friction is the force that prevents solid surfaces, fluid layers, and material components sliding against each other from moving in the same direction. Friction is desirable and necessary for providing traction and facilitating movement on land. For acceleration, deceleration, and changing direction, most ground vehicles rely on friction. Sudden traction loss can result in a loss of control and an accident.

Complete step-by-step solution:
A force that holds an item at rest is known as static friction. The friction encountered when humans attempt to move a stationary object on a surface without actually initiating any relative motion between the body and the surface it is on is known as static friction. It is defined as the frictional force that exactly balances the applied force throughout the duration of the body's stationary condition. The static frictional force is a self-regulating force, which means that it will always be equal to and opposite to the applied force. Static friction is the friction that exists between two surfaces in contact when there is no relative motion between them. The sliding friction does not begin to operate until the relative motion begins. It has the same amplitude and opposing directions of action on both surfaces in contact. When two surfaces move in relation to one another, or have a tendency to move in relation to one another. The maximal static friction force is independent of the contact area. The maximum static friction force is proportional to the normal force, meaning that as the normal force grows, so does the maximum external force that the item can withstand without moving.

Note: When an object is poised to slide across the surface of another object, the greatest amount of static friction comes into play. The body begins to move when an external force is applied that is larger than the limiting friction. Static friction cannot be evaluated until the motion has begun. Kinetic friction is a new form of friction that comes into play.
