Friction can lead to wear and tear on moving parts of an object, causing them to degrade over time. This can decrease efficiency and performance, ultimately hindering the object from working well. Additionally, friction can generate heat which can affect the functioning of the object's components.

A car engine can stop working well due to friction if the components, such as pistons and cylinders, experience excessive wear and tear. This friction can cause decreased performance and eventually lead to engine failure.
A rolling boll on a plane surface will stop after some distance due to friction.
static friction. Static friction is the force that resists the motion of an object when a force is applied but the object does not move. It is present when there is no relative motion between the surfaces in contact.
The friction force acting on an object moving through air is called air resistance or drag. It opposes the motion of the object and its magnitude depends on the shape and speed of the object, as well as the density of the air.
Friction can reduce the efficiency of moving parts by generating heat and wear at the contact points, causing parts to degrade and requiring more energy to overcome the resistance. High levels of friction can also cause objects to seize or lock up, preventing them from functioning properly.
