Maximum value of friction depends upon the normal reaction and normal reaction can be impulsive, so does that imply friction can be impulsive?

Friction is a force that resists motion between two surfaces in contact. It is caused by the microscopic irregularities and interactions between the surfaces.
Impulsive friction, also known as kinetic friction, occurs when two surfaces are moving relative to each other. It is typically greater than static friction and can cause objects to slow down or come to a stop.
Non-impulsive friction, also known as static friction, occurs when two surfaces are not moving relative to each other. It is typically less than kinetic friction and can prevent objects from starting to move.
The amount of friction depends on several factors, including the nature of the surfaces in contact, the force pushing the surfaces together, and any external forces acting on the objects.
An example of impulsive friction is a car braking on a road, where the brake pads create friction with the wheels to slow down the car. An example of non-impulsive friction is a book resting on a table, where the friction between the book and the table surface prevents the book from sliding off.
