Impending motion-
It refers to the state just before surfaces start to slip. In this case the static frictional force reaches its upper limit.

Impending motion is opposed by static friction..because it is the time when the object is going to slip in one direction...so that slipping of the object is opposed by static friction(max)...as soon as it starts moving friction becomes kinetic

Static friction is the force that opposes the impending motion of a body. When an external force is applied to an object, the object tends to resist the motion. This resistance is due to the interaction between the surfaces of the object and the surface it is resting on. Static friction comes into play when the object is at rest and prevents it from moving.
Static Friction Explained:
- Static friction is a type of frictional force that exists between two surfaces in contact with each other.
- It acts parallel to the surface and prevents the object from moving.
- The magnitude of static friction depends on the nature of the surfaces in contact and the force applied.
- Static friction increases with the applied force until it reaches its maximum value, known as the limiting friction.
- The limiting friction is given by the equation: F(max) = µs * N, where µs is the coefficient of static friction and N is the normal force acting on the object.
Comparison with other types of friction:
1. Sliding friction: Sliding friction is the force that opposes the motion of a sliding or moving object. It comes into play when the object is already in motion. Unlike static friction, sliding friction acts against the direction of motion.
2. Rolling friction: Rolling friction is the force that opposes the motion of a rolling object. It occurs when a wheel or a ball is rolling on a surface. Rolling friction is generally lower than sliding friction.
3. Kinetic friction: Kinetic friction is the force that opposes the motion of an object that is already in motion. It is the frictional force experienced by an object sliding or moving at a constant velocity.
Importance of static friction:
- Static friction is crucial for objects to stay at rest and prevent them from sliding or moving unintentionally.
- It allows us to walk, drive vehicles, and perform various activities without slipping or losing control.
- Static friction also enables objects to be stacked or placed on top of each other without collapsing or sliding.
Conclusion:
Static friction plays a significant role in opposing the impending motion of a body. It prevents objects from moving when an external force is applied and allows us to interact with our environment safely. Understanding static friction is essential in various fields, including mechanics, engineering, and everyday life activities.
