Question

explain the static and position fraction with suitable examples

Answer 1

If you try to push your couch across the room, the first push is the hardest part. Maybe people assume that's nothing more than psychological, but there really is a physics reason for it. The reason is static friction.

Friction, in general, is a force that makes it harder for two objects to slide alongside one another. Static friction is the friction that exists between a stationary object and the surface on which it's resting.

A frictional force occurs when you try to push an object alongside a surface

Once the objects have already started moving, kinetic frictiontakes over. This is the friction that exists between two objects moving relative to each other. Kinetic friction isn't as strong as static friction, and so it is easier to keep the couch moving
